Doggy,
We have a team that struggles to get rebounds already with Bosh at Center and Haslem at PF. You really think Beasley, who we know first hand hates contact and doesnt rebound worth a shyt, will be able to get much playing time?
Breh, who do they have on their team that rebounds that should get minutes over Beasley? You're making it seem like he'd be taking minutes from Ben Wallace or something. Those rebounding issues are going to exist regardless of him being there or not, the only hope they have of fixing that problem is Oden, and he will be on a minutes limit and probably won't even play the first month or two.
The SF core off the bench behind LeBron is -
Shane Battier, Rashard Lewis, James Jones....
Which one of these dudes rebounds? You're honestly going to tell me Beasley can't be an upgrade over these cats?
