Coaches are supposed to build around the talent they have, not completely change it, look at what UF and the Broncos had to do with Tebow. Both teams did ok, SH tried to fit a square into a round role and it didn't work...and got him fired. BJ was always good on the run and could make plays running or passing, his biggest issue in my opinion was always trying to do too much and usually led to the turnover or big sack. With that team and talent around him he knows he can dump the ball or throw it away and move on.
I have to imagine WT is building around the talent he has and utilizing their strengths and developing their weaknesses to put a game plan together.
