I can safely say the time to relax is over.
Hmm, it's hard to say. We were still without IT, and Horford and Brad made some uncharacteristic errors that usually don't happen, along with Bradley being worse than usual down the stretch. Before that it was Crowder in the Raptors game with terrible decision-making and shot selection down the stretch. The game before that it was IT coming in and giving up an 8 point run and the lead (though I still don't count the Houston loss as a fair loss since the officials legitimately stole a point from us with incompetent officiating).
So I'll say this - without some of our rotation guys our margin of error is extremely thin, and we just simply can't make the type of boneheaded plays that we have late in the 4th the last couple of games.
I guess another thing to consider is that it's not just on one or two players. Almost every single one of our rotation players has had some bad play and/or poor decision-making down the stretch of a game that has hurt us. I just think with our injuries and lack of continuity/chemistry right now that we have an extremely small margin of error and just can't afford these mental lapses that we've been having.
