I think Delaney's opportunities were too limited and rare. 1 minute at the end of a quarter, then Sutton comes back in, 2 minutes in an already decided game. I never seen him receive ample opportunity that I'm very sure he would've been promised.
Mason was never going to impact games greatly but he was a fan favourite and a long time player. I think he needed to be in the games for 3 or 4 minutes early on then see what happens. Get everyone in to keep their interest levels high, it's natural for young guys to be uninterested after 4, 5, 6 DNP's or near enough.
Josh Jenkins was a contributor on the team, he started one game and started well but was then sat for a long time, I have no doubt he was uninterested in the last few games due to Summerville's antics which caught many sponsors and onlookers off guard.
Losing a local role player, the main 'reserve' poin guard and the sixth man (usually) will hurt them down the stretch
