Bryant only got hurt last night, so it's pretty early to criticize the DL/no DL decision. Heyward only has a cut, and they put him on the DL after giving him 3 days to heal and then discovering it was worse than expected. That seems like about the right balance to me, I don't want them DLing everyone the moment they need to miss a game or 2 and forfeiting the option to have those guys back sooner, but you do have to balance going short handed on the bench. Russell and Zobrist are less clear cut, but those are also shoulder injuries which are tricky to evaluate(especially in Zobrist's case since it was mostly with hitting from one side of the plate), but I see the argument more that they could have been DLed/DLed sooner.
