re: Am I wrong for not putting this failure of a season all on JJ?

All?, probably... Every team has unique dynamics and IMO we've got a 'once in a lifetime' type scenario going on. JJ hasn't managed it well (I.e., Simmons shutting down when he should take over, intense defense and press, game clock/timeouts, and basic heat of the moment/during game strategy).

Ben is the leader with no leader qualities. So sad these kids can just go off in a year. He's going to have a lot of problems.
