The operative word is "transition"....and with all those losses there is no transition...just an abrupt change from A to B.....kinda like Gus tried to do after Cam left and Gus did not have a QB to run his style offense....in fact this looks a lot like 2011 season to me except we had a better Offense with a bunch of players who had won a championship.
Abrupt changes are not easy to make....as we are seeing.
That's what made Steve Spurrier so great at Florida. He ran the same offense every year. He recruited players to fit that offense
