Yost would be an incredible hire. What do people see that they don't like?
The type of offense he runs, while incredibly productive, has a ceiling.
The reality is, that ceiling for the offense is so much higher than our current status, I, personally, don't care. If you're running screens all day...you're going to be just fine versus most teams, but the big boys sniff that **** out like blood hounds and eat you alive. He's been around offenses like Pinkel's, like Leach's and its super productive, but its also a bit soft. Mario's OC (before he took the UNLV job) Marcus Arroyo ran screens all day long...and look at what happened when they played Auburn -- or read some NFL scouting reports on Justin Herbert or see what Blaine Gabbert did.
This is not a criticism for a dilapidated program like ours. He'll do great here if he comes - we'll probably break school passing records and have the biggest improvement among all FBS teams in total offense, passing offense, and yards per play. But, there is a bit of a ceiling to whatever he does if/when we ever get back to playing respectable football.
Also, he doesn't really run the football as a playcaller...and this is a big problem for me, but we suck so bad, I'm willing to overlook what I'd ideally want for something that looks modern. I'd rather go 8-4 or whatever throwing for a bajillion yards and scoring a ton of points then going 8-4 with whatever the fvck we've been doing over the past two decades.
In a perfect world we find an OC that pushes the ball down field and also runs the ball at a pretty decent clip (~40 times a game?). If we can't get that...well...I'll settle for Yost or Graham Harrell types that just chuck it all day.
