Except this didn't actually happen...The young players got big minutes and big roles last season. Such a tired false narrative. Focusing on X's and O's would make for a stronger argument. Unfortunately, few have the requisite understanding of the game (myself included) to make that argument (Franklin's actually one of the exceptions).
FWIW, while I'm not the least bit upset Ty's gone, and have been more than pleased with the growth of the team under Snyder, I think Ty was put in no-win situations every season in Utah:
2010/11: Deron, Sloan and Phil Johnson all leave. Ty tries to pick up the pieces.
2011/12: Lockout season, little communication with players, no real training camp. Team makes the playoffs.
2012/13: Lame-duck team, with leading vets likely on the way out, and young players waiting for their chance. FO decides not to make moves to usher in the youth movement. Vets (Sap, AJ, DMC) allowed to walk in free agency.
2013/14: Lame-duck season for Ty. No one expecting him to be re-signed, given task to make strides defensively with a team filled with young players who hadn't ever been handed lead roles prior to the season.
