Overall the team gets better, no doubt... Although a young PG like DWill would be much better, it's not easy to get em, it's tough to know what they are still planning for trades...
There's no use for Sessions now, so he's likely to be traded... The Lakers might still be going after D12, but would prolly have to give up Bynum another young guy, instead of Gasol who would be much better for the Lakers... There's the whole age problem, but no matter what it's a better team already than last season...
