A lot of this has already been hashed out, but wanted to add my own thoughts.  I don't think it is an issue of being soft, it is an issue of interpersonal relationships.  That's what sports teams are about.  Teammates don't have to be best friends.  Teammates don't always have to be nice to each others.  Teammates do have to respect each other.  Once that is gone, it is hard to get past and achieve success.  Maybe this is a breaking point.  Maybe it was already gone (and I'm talking both ways).  I don't know, but I don't think these kinds of comments are helpful at the most critical juncture of the season.  Do they make sense during a mid season swoon?  Sure, I can get behind them then.  But there is a reason for "playoff beards" and the like.  Once you get to the post season, it is one for all and all for one typically.
It's not about giving an "attaboy."  It is about having each others back.  I feel like he had JR's back in the post game press conference he walked out on, obviously being baited to throw JR under the bus and he refused to do so.  Other than his "be better tomorrow" comment (reporters have a job too), I totally agreed with his answers and refusal to be baited.  But, saying publically he doesn't have to carry his team more than he already does is drawing a line between "me" and "them."
Honest question, because I don't know.  While Jordan trashed his teammates in practices, and maybe even huddles during game, did he do it during press conferences?  I seem to remember him having an extremely polished and possibly too perfect (ie fake) media persona, so I can't imagine Jordan doing the same to a teammate in the media.  Correct me if I am wrong.
