Me too.
My answer is: d) None of the above.
It's less about Foley than it is the players he is coaching and the philosophies of his predecessor. The players themselves are young, immature, and un/under-developed. The previous coaching staff pushed theory over practice and seemed to expected the players to be motivated to push themselves, which is generally not the case (Exhibit 1:
Courant Article from last October; Exhibit 2: Players like Xavier Hemmingway having a hard time putting on 5 lbs. let alone 50 to approach the physique necessary to play Div. 1 college football). 1% of high school football players play college ball. Further, 1% of college players play in the pros. Pros are generally self motivated, but they didn't get there on their own. Even if they did, UConn is generally not in on that 1/100th of 1% of players.
I do not consider Foley to be a god. If he were, these Freshman and Sophomore linemen would be opening Mack truck like holes and Whitmer would have 7 seconds to throw the ball every play.
