... Again we'll roll out the same group and expect different results.
Thanks for the clarification. It still doesn't address the question of whether the coaches are playing the best choice among those they have or not, but no point beating that dead horse. Moving on, though, there are several reason why I think QB play will be better this fall:
OFFENSIVE LINE
The first reason is the offensive line. The QB doesn't play in a vacuum. For runs to work, the line needs to make room. For passes to work, the line needs to give the QB time. Last year Ohio had one of the least experienced offensive lines in the country, and that meant little room to run. That in turn meant that the offense became one-dimensional - forced to pass, which allowed the defenders to get after the QB, forcing them to scramble and often throw off balance. Honestly, no QB is going to look very good playing behind a line that includes (at times) 3 true Freshmen.
The most appalling example of line failure was the CMU game. CMU had so little respect for Ohio's running game that they played essentially the who game in a nickle defense. Ohio would line up with 8 players in the middle of the field, and 3 wide receivers, and CMU would defend with 5 dbs and 6 in the box. That meant Sprague, when he passed, usually had to throw into double coverage. Normally when a team does that you just run the ball and take the 5 easy yards every play until the other team brings more players into the box. Take away one 49 run by Daz, and Ohio's running backs gained only 39 yards on 15 carries, 2.6 yards a carry, and you can't sustain a drive with that. Since running was futile, Ohio passed (into double coverage), and Srague completed 1/3 of his passes. Could Ohio have brought more TEs in, and improved the running game? No, that would make it worse. Luring a defender out of the play by lining a receiver wide is just as effective as blocking him. With 3 WR being covered by 5 DBs, that meant Ohio was trying to run the ball 8 on 6, and failing. Bring in anther TE, and they will cover your 2 WR with three DBs, and put 8 in the box. Now you are trying to run the ball 9 on 8. If you can't run the ball 8 on 6, 9 on 8 is not going to be better. It will take me a long time to forget that game....
For 2015 all the starters on the offensive line, and all of the backups return, and in addition two jucos and a former starter who sat out last year due to an injury are added to the mix. The offensive line will be much improved, and that means a more effective running game, and more time to pass, plus the ability to mix up play calls, rather than being forced to be one dimensional. The same QB will therefore look much better, not because he is better, but because the circumstances around him make his job much easier. Remember - a play-action pass is not going to work very well if they don't fear the run and the pass will have to be perfect, but when the do bite, and come up fast to stop the run, the receiver is ofter wide open, and the pass will be easy.
RUNNING BACKS
Presuming he doesn't get hurt this year, AJ will be a load. I expect Daz to provide a change of pace, and either Irons or Brown, or both, to jump into the mix as well, and provide some excitement. I don't expect fumbles this year, and so these running backs, combined with the improvement of the offensive line will take a lot of load off the QBs.
EXPERIENCE
For a QB, a year of experience means a lot. I expect that each of the QBs spent a lot of time over the winter looking at film of what they did last year, both right and wrong, and trying to learn from it. When a QB (or any player) has to "think" and react they are slower and less accurate than if they can just react. This is commonly referred to as the game "slowing down for them".
These are the reasons I'm not overly concerned about the QB position. Even if the QBs didn't improve, the improvement in the line and running backs would make their life much easier, and they would look better, but I also expect them to improve. I think any of the three will look better in 2015 than any of them looked in 2014.
