They just seem to be exhausted right now. And it's evident how much they miss Leonard.
Green, Tiago and Neal just aren't top level players, Neal's always been a hit and miss role player and Green is still trying to develop his game. Tiago's game is getting much, much better and he's a good contributor but he certainly can't carry the team. Not sure what I think of Diaw right now, The rest of the squad? well they are what they are...
Tony's worn down, Manu's still not right, SJax is hurting so it all falls on Tim's shoulders and he's doing a great job of holding things together.
They'll be fine, especially after they get some rest over the next week or so.
Since you can't fix stupid, at least you should be able to prosecute it!
