Speed at corner

Where is it?

I really like the guys we have on the roster, but aside from Couch and Bethel they aren’t burners. We need to inject some speed.

The local crop doesn’t seem to have the answer. Gray is running 4.8. Harrell had a PR of 11.76 in the 100M last year. Stanley is quicker than fast.

I hope somebody shows some juice at the Opening on Sunday.

Are you starting to wonder about Rumph’s recruiting?

:img-0076c:
 
The bottom line is richt talked about speed when he got here but he didnt do much about it. Thomas is our only legit plus speed WR. Wiggins and Njoku are fast for their height, I guess, but not burners. Pope is quicker than truly fast, though he’s fine as far as speed goes. Our safeties arent burners. None of the LBs richt recruited are. Lingard is legit fast. Him and Thomas and Bethel are about what richt has to show on speed.

11.07 is much closer to 4.55 to 4.6. Its nowhere near 4.3.. 4.3 is for guys running 10.3

The problem here is you actually think you know WTF you’re talking about.

That’s 11.07 100 METERS vs 36.6 meters aka the 40 yard dash. Do you even understand the strength required to maintain that speed over 100 meters. You don’t.

Its one thing to be fast, another to be athletic...and I had a post long ago about this...we've had horrendous athletes on this team for a while now. Especially on the lines. Incredibly overrated athletes on our team for years by our fanbase, too.

We've had very few elite athletes on the team over the past few years...and a lot of bad ones.

100m runners don't run the same style. There are many different body types and styles. Some start faster in the splits, some end faster in the splits. Not sure what you mean by "Maintaining speed", that's not very specific. Maybe you should lead below and learn something.







After NFL combine every year there will be some fans arguing how players can perform in 100m sprint race. Also, fans will also argue what is the real 40-yard dash record ran by Bo Jackson when there is electronic timers.

Therefore, I do some researches on how the time split of 100 meter sprint athletes can be related to a short distance run. I am using the result of 100 meter Man 2009 Berlin Championship Sprint where Usain Bolt broke his world record 9.58s here (data can be retrieved here).

Normally a 100m sprint athlete reach his top speed at around 50m, consider the acceleration of athlete is changing it is hard to compute a very accurate result. Fortunately the 20m time split of athlete is highly linear (Graph of some athlete's 20m split and their R2 value are often 0.999 or higher). It is due to elite athlete reach their 90% speed near 20m and the acceleration and deceleration is small compare with their speed (Speed of medal winner can be found here).

As the graph plotted above the slower athlete tends to have a more gentle slope and smaller y-intercept in their 20m split graph. Therefore, by comparing the slope and intercept we can find how their time for short distance change with their 100m time.

By using all available time in 2009 Berlin Championship relationship of their slope and intercept is plotted as below.

Slope

Y-intecept

However, the error will accumulate when the athlete is slower.

Error in 100m time

To tackle the problem I use estimated 100m time to normalize the estimated time to actual 100m time in order to make it more accurate. This is the excel file which consist all the data and graphs.

It has a calculation tools to calculate 40-yard dash time out of 100m time. Be careful that the data will be extremely inaccurate after 13s 100m

A quick convert or tl;dr of the calculation



100m timeEstimated 40-yard dash
9.794.2
10.274.3
10.644.4
10.954.5
11.214.6
11.454.7
11.734.8
Finally it is some comparison of NFL player time and estimated time (Note that NFL combine and 100m sprint is running on two types of floor and 100m sprint time is their best time, so small variation is expected). As players compete much more times for their personal best, feel free to add ~0.05s for more probable calculation.

Richt complained about speed at wr and he did fix it. Got thomas, harley, pope. Wiggins can run. At the time other than richards and coley who were fast you had berrios, langham, harris, mullen, cager, and none of them were fast.

Not aure who you are talking to. I am not a proponent of fast without talent, and never have been. So we may agree on that. But that is neither here nor there. It still matters that you have speed, and it matters a lot when you have overall very little elite speed. Ideally, you have fast and athletic guys, but one way or another, we need more speed at DB and WR.

I’m high on the talent of Campbell for sure but just keeping it a buck anyone and everyone was doing it not just good teams. Probably just lost some confidence during the season last year

Eh. Berrios was quick. Had one of the best short shuttles on the team. Maybe the best. Coley was fast. Richards was. Thomas is. I forgot about Harley because IMO he’s not a very good receiver. Wiggins is not a burner. Reasonable speed. No problem with any of them individually, but overall, we need more truly fast guys, including for returns. You’re talking about the school that rolled out hester, moss, parrish, benjamin. Let’s not settle for ‘okay.’

Those dudes are rare. Kids are not growing on trees with that type of speed. Its rare you see a team with multiple guys at 1 position running sub 4.5.

Even some of the best cbs this year didn’t run in the 4.4s. Deandre baker(he not that good imo) but a solid corner nonetheless and he won the throrpe but he’s closer to a 4.6 if that and he’s only like 5’11 185. Not sure what greedy Williams runs but I dont Think it’s a sub 4.5 either

Berrios shuttle time in HS before his injuries was a 3.81 which is good for top5 time ever in the NFL combine. His time dropped to a 4.18 by the time his NFL Combine rolled around.... which is still excellent.

We’re not ‘a team.’ We’re miami. We want to compete for hardware, not also-ran ribbons. We are in speed central. It’s our legacy, too. Andre Johnson is fast. Thrill Hill was fast. Kevin Williams was. Yatil Green. German. Dorsett. Portis. L. Miller. Buchanon. A. Burns. DVD. Bruce Johnson. We’ve had lots of fast guys. We just havent been recruiting speed well recently.
 
That's where Henderson is missed like crazy to me. Thankfully the dbs oress well and for the most part aren't making real mental errors plus our dline does work but the speed is our cbs weakness and has for a few years
 
They can be if the staff focuses on it.

The Butch years had a lot of speed.

At the WR position, Moss had a 4.31, Daryl Jones was a 4.3 or 4.4 and Andre Johnson was a 4.4 something.

Many of our RBs during that time were burners - Edge, Portis, McGahee. Davenport could move, but lost some speed after the knee injury against Ohio St. And James Jackson could move - a 4.55 at the combine, but he sure looked like a 4.4 guy from what I recall from seeing him break some big runs off. Maybe he had a slow combine.

Hopefully this new staff will continue to build the level of speed on the team. We need more.
