Except the reasons why people were down on the Landry signing still apply today: we paid a lot of money for a backup PF, when what we needed was a backup center, and/or a rim protector. And we still need those things. Nobody who was down on the Landry signing said he couldn't play.
I reject your 'no coach' premise. Mike Malone owes no loyalty to Ramon Sessions, and I have a hard time believing that he believes that Sessions gives him a better chance to win.
It has nothing to do with loyalty. The law of averages say Ramon will do better. He's only 28 and I highly doubt he just lost all of his abilities overnight.
