Since there's no way we're this bad of a team, is it possible that our team is really tired right now? Our best players right now are Rasho, who barely played in the first months, and TJ, who missed lots of games as well. Parker and Bosh
are absolutely horrible, and they are usually playing the heavy minutes. Jose is not playing great either, and he also was overplayed prior to March. The subs are playing pretty much like they done all year, one good game, one bad - I don't see anything particularly different about them.
I hope they are tired, because the alternative is that they are tired of Mitchell, and I can't find any arguments for this (other than the bad play).
