I'm nowhere near an X's-and'Os expert and won't pretend to be, so all I'll say is this: it's early.
Two games in last year, the theme on the boards was Miami's horizontal offense. Everybody was asking why we weren't challenging deep. By the end of the season, Morris and Co. were the top vertical attack in the ACC.
UF presents a unique package with the best pass-rushing DT in the nation and the best set of corners in the nation. That's enough to make any QB (even future first rounders) very uncomfortable. Add in the horrendous running on first and second down (average of 3rd and 11.5), and Morris is going to have a tough time.
The telltale sign that Morris is rushing things is when he starts missing high, like he did a few times to Dorsett. UF will do that to you, unless you are an unshakable #1 overall pick like Teddy Bridgewater. I thought Morris greatly improved his redzone accuracy and touch throughout spring and fall camp, and he showed that on the TD toss to Herb Waters. He'll continue to get better.
As for Coach Coley, this is 100% pure speculation, but I wonder how much last year's FSU/UF game played into his mind. It was a tight game until UF's defense took over late and EJ Manual self-destructed. I wonder if he was playing not to lose in the second half.
