Is your impression that this season's performance so far is due to lack of effort? That may play a part but working harder at something that isn't working won't make a big difference. I hate to say it but a lot of the pre-season concerns - Giles not coming back at close to 100%, Jayson being a black hole on O, no PG, and too many shoot-first guys - have been accurate so far. Combine that with injuries, suspensions, Matt Jones regressing, and Bolden not yet contributing much and that's where we are.
On the other hand, this time in 2015, we all had similar concerns. This year's team - outside of not having a PG - has more talent than 2015, and I suspect that like that team's, our D will be much better in March than it is now. If we can find a reasonable imitation of a PG, I think we'll be good, and possibly even very good.
