Trevor Ariza scores 15.9ppg on 15.3 shot attempts + 3.5 FTAs + 2.6 turnovers. The man is not a scorer.
Ariza's defense + rebounding have also dropped considerably this season due to the increased demands offensively. He hasn't been able to sustain his previous high quality work in both departments. It looks like it will be one or the other and he's a lot more effective as a fifth option.
Shane Battier turns 32 years of age before the start of next season. How much use is he to a young team?
It's a terrible trade package.
Again, a couple of things. You mention that Ariza has suffered now that he is no longer the fifth option, but in going to Memphis he would become at best the 4th. Isn't it possible that his defense and rebounding would go back up now that he's no longer being asked to carry the offensive load.
As far as Battier being to old for a young team, how useful was Bibby to the Hawks? Brad Miller to the Bulls?
Ariza -- So you're getting the 11-14ppg + 6-7rpg + very good defense player. Yes, I believe that's the player you'd want to get and he's capable of being. Or else the horribly inefficient scorer + reduced non-scoring contributions. I'd take the role player version myself.
Bibby and MillerBrad Miller's primary value is as an expiring contract. Not a player. As such, I like him very much.
I did not like the Hawks acquiring Mike Bibby. I thought it was a waste of cap space and has served to limit their development. I also, as I'm sure you've guessed, don't believe he deserves much credit for the Hawks improvement. Ditto for Jamal Crawford.
Rudy Gay(1) Rudy Gay's current + past on-court performance isn't much to write about. He's a comparable talent to Ariza in overall impact. He just does it in flashier ways. That has given him more of a reputation and more trade value. The Grizzlies should try to utilize that value instead of swapping him for a comparable talent.
(2) Rudy Gay does have considerable potential. He can still improve greatly as a defender, as a rebounder, and with his scoring efficiency. I doubt he'll ever be a franchise star but he could become a very good third option on a contender for the next 7-10 years.
Losing that potential for a role player is a poor decision.
Trading that player for an established star, a young prospect with considerable potential, or future draft picks is acceptable.
