For whatever it's worth, I don't think Murphy was ever "healthy" this year. His poor play currently -- or prior to his ankle injury -- is more than just rust / lack of conditioning. It looks like he never recovered from his back and leg injuries, which is what New Jersey was saying when they weren't giving him playing time.
Many people assumed that Murphy was benched due to a grudge with Avery Johnson, but it looks like it was more than just a personality conflict.
I'm not criticizing Danny here -- the upside for Murphy was worth the gamble -- but I never quite understood why fans have pointed to Murphy's health as a positive for him.
Yeah, I think your right on this. He just has not looked comfortable out there, and I think its more than mental. Physically, he just does not look right.
With that said, I still feel more comfortable with him at the end of the bench than Semi. I am hoping having this week of practices, and another game where he can play bigger minutes, and hopefully get a little rhythm going. Even if its purely as a decoy, having that extra shooting big man on the bench is more valuable to this team than Semi would have been.
The problem with Semi is that he is not strong/physical enough (at least not right now) to really bang inside, but he is not skilled enough to play on the perimeter. Plus, he is a rookie. His hustle has gotten him a long way during the regular season, but I am not sure that translates that well to the postseason, when everyone is going that hard.
So, he wouldn't really make a difference if Shaq is out, and he also can't provide the versatile, in case of emergency PF that Murphy can potentially be.
Either way though, I hope whoever is in that roster spot is not even dressed for the playoffs, because if they are, then this team is probably not in great shape.
