I like the Shawn Marion signing, but I don't think it really moves the needle that much for the team.
Yes, he was a very good player for quite a long time. Yes, he is probably a better value than a 40 year old Ray Allen at vet minimum salary.
However the Cavs are not getting the 2005 or 2010 Shawn Marion. They are not even getting the 2013 Shawn Marion. They are getting the 2015 Shawn Marion. The 2015 might be a bit better than a minimum salary player, but not a lot better. He's mainly a jump shooter these days. When he was on the court last season,
the Mavs offense suffered, the rebounding suffered, the defense really suffered. There's s reason why Dallas wasn't fighting to keep him.
Marion strikes me more as strategic depth signing. He can fill in at multiple positions. He'll be great to have around if there's an injury or a trade. He's going to be a lot better than a d-league call up. I'm not sure he'll get higher than the 8th guy in the rotation on most nights.
