Actually, plenty of people have given suggestions that you have shot down. You just have to accept that other people evaluate talent differently, and have different opinions than you. Just because you don't like a player, does not mean they are a legitimate option.
Just because a guy is mentioned as a bench option does not mean that anyone sees that player filling the 6th man role. I keep reading that we should use the MLE to sign a bunch of guys who would be lucky to be 8th-10th men on a championship caliber club.
That's why Posey is so valuable. He has already proven that he can be the 6th man on a championship team. He has proven this twice already. Again, there is no one player available who could fill his role.
I think Barnes can fill this role. I think Finley can fill this role. I absolutely think Kurt Thomas can fill this role. So could Bonzi Wells. Keyon Dooling could potentially also fill this role. Najera is basically a perfect player to fill that role from the PF spot, and brings many of the same intangibles. Mo Evans also could turn out to be a similar player to Posey when you put him with other great players.
I absolutely think there is a risk in bringing in anyone else new. We don't know how they will fit into the system, and we don't know if they are one of the guys who are going to respond well to playing with such good players.
But the fact is, Posey is not that much more, if any more talented than any of those players. There is only so much of a premium we can pay, just because of his experience, and for the knowledge that he has done it before. Any one of those guys could do as good a job, or better than him next year, but we don't know it for sure. That is why we would offer him the full MLE. But it is not reason enough to put the teams financial flexibility down the road in jeopardy.
