I normally agree with a lot of your posts but you lose all credibility and I have to question every post when you say Rosier would win the QB job this year. LOL
Allow me to explain- I was also the guy who, after the 2017 season, was betting other posters that Rosier wouldn't finish 2018 as the starting qb. It may sound like a contradiction now to say he'd likely start in 2019, but it's not. Here's why. Miami was coming off a 10 win season in 2017. Many fans thought we were close to playoffs and if we had just a little more offense, Rosier could lead us to the promised land. Why was I so sure he wouldn't finish 2018 as the QB? I looked at his stats- his completion percentage was atrocious. It didn't matter if it was against good defenses or bad defenses, he was not an accurate passer. However, despite his inaccuracy, he didn't turn the ball over. His stat line up to the ACC Championship game was 25 passing TDs, 5 rushing TDs, and 9 INTs. Those are pretty good "game manager" numbers. That meant that his ceiling was probably a 10 win QB, but due to his lack of accuracy he had zero chance of beating a team like Clemson or Alabama. A lot of us thought that Miami had the talent to make a serious run in 2018 for the playoffs, and I knew that it couldn't happen with Rosier. We wouldn't have even a puncher's chance against teams that had elite defenses AND could put points on the board. I figured Richt knew this as well, so I assumed he'd try to find a Trevor Lawrence-type talent between 2017 and 2018. I didn't know what we had in Perry, only that he wasn't putting in the work to be a good QB, which wasn't a good sign.
So if I think Rosier wasn't good enough to finish 2018 as the QB (assuming the HC wanted to have even the tiniest chance of beating Clemson and getting into the playoffs), why do I think he'd be the starter in 2019 over our current crop of QBs? You have to understand what a defensive-oriented first year head coach is going to prioritize. What is the #1 most important trait for a QB in the mind of a defensive-oriented HC? A qb who does not turn the ball over. Is Miami going to a win a championship in 2019? No. Do we have the talent to win 10 games? I think yes. Diaz is fully aware that he doesn't have a championship caliber team yet, so what he needs most is serious momentum to carry through his first year into the offseason. A 10 win season in his first year as HC would be massive for recruiting hype. That's how you can recruit a Trevor Lawrence-type QB or get a plug and play transfer QB like Jalen Hurts or Justin Fields. An 8-4 season (or worse) would be a a disappointment to fans, and more importantly, recruits.
So in Diaz's first year, Which qb, of the ones on the roster plus Rosier, would be most likely to win 10 games? Probably the last QB to win 10 games.
Here's how they stack up:
Perry: terrible offseason decision making, two years in a row. Holds the ball out to the side when running, easily knocked out. Takes lots of sacks.
Williams: bad attitude as well, threatened transfer. Seems to be having a hard time reading the field, is the most INT prone of the QBs in practice
Martell: ? Some posters (even in this thread) put him behind Perry and William, talent-wise (that being said, he's still my guess for the actual 2019 opening day starter as I think his HS numbers show he SHOULD be the most accurate QB on the roster)
Rosier: won 10 games in 2017. Good runner, poor accuracy. Dependable game manager. Not turnover prone, but completely helpless against elite defenses.
You can counter and say that Rosier fell apart in 2018, but the entire offense fell apart in 2018 and that's not all on Rosier. The offense scheme was so bad (no matter who was at QB), that our HC suddenly retired after realizing he no longer had that ability to call plays. The QB coach is still unemployed and was among the worst QB coaches I've every seen at ANY program. He made D'Nofrio look competent by comparison. So I just don't put much stock in 2018.
To put it another way- if I told you that I'd give you $10 million to deliver a package within 48 hrs from LA to NY (43 hr drive) and gave you 4 cars to choose from: 3 Ferraris or 1 Toyota Camry with 15 k miles on it (past the break in period), which car do you pick? Personally, I would take the most reliable (Camry). Speed doesn't matter if the car breaks down.
If you had to bet on on who is most likely to win 10 games- I think logic dictates that the previous QB who won 10 games (dependable) and who fits what a defensive oriented HC wants (not turnover prone), then Rosier would the guy. He would NOT be the likely starter in 2020 assuming that the HC thinks he can make a championship run. Either one of the other QBs on the rooster would have developed by then or he will have recruited a stud in the offseason. But in Diaz's first year, in a contest to figure out who is most likely to get 10 wins, Rosier would beat out the other 3.
