re: should JJ feel betrayed by LSU fans?

Who gives a shite how he feels?

The game is about performance and the team moves best as a machine when top performers are at every position. JJ did not consistently play like a top performer.

This shite ain't hard. Kids do it all the time. Name one quarterback with three years of significant playing time who played worse.

A great QB does not regress in his 3rd year. That's the year you're supposed to establish yourself. So if you can't establish yourself as a top performer with that much playing time, you have earned the uncomfortable position for coaches and fans to wish they had a better option than the status quo.
