We got Yates (from what I've heard) because everybody else looked at him and thought he was too short to play QB in a conventional spread. Paul looked at him, saw Ricky Dobbs, and went after him hard. Then Yates had a breakout senior year and all of a sudden looked like Russell Wilson. Collins saw that and, while not enthusiastic, worked hard to keep him; it was too late to find another QB. Now we'll have to see if Yates gets his chance or whether the coaches have a height/weight fetish instead of a performance one. I hope it's the later and I think it is; there's been no reason to play Yates and he needs the extra time to get up to speed, just like most QBs do.
I do think that Yates can be a killer in any offense. The level of talent he showed in high school was very impressive. Now we'll get to see what he has. It should be fun to watch.
