Better Talent:
Incoming: Miller, Love, 2 stiffs
Outgoing: OJ Mayo, 3 stiffs
Better Fit:
I think Al is fine at center, especially in today's NBA. Ideally you'd have a solid 5 and 4 that both compliment him, and he'd play both positions. Well now they have the PF. At anyrate OJ Mayo is not a PG (IMO) and redundant with a lot of what Minny has in Foye and Brewer (but OJ is much better - I'll agree.) Anywho, fit for Minny is more about Salaries and Years, and (in Miller's case) trade-ability.
So McHale runs out a team of Jefferson, Love, Gomes, Miller, and Foye with Hudson, Brewer, Smith, and Collins off the bench. Sure its problematic to have so many redundant pieces - but I think Gomes and Smith both leave at years end if they aren't traded sooner. Plus Cardinal's shorter deal means end of next year they won't have any bad deals on the book. Nice.
UPDATE: Just to clarify according to hoops hype, Minny has only Al Jefe under contract after next season. They'll be in good position to trade this year at the deadline, and the next year. Or they can just let everyone go and be WAY under the cap.
