Quite simply, this years playoffs have hammered home 2 very important lessons...
1) Building a team around 3 max contracts is a huuuuge gamble that will rarely, if ever, pay the dividends it does on paper. Miami, with it's 3 stars, is always one injury (Bosh) away from mediocrity. Because depth will ALWAYS be compromised, an injury to one of the stars and the team is screwed and scrapping.
2) A great coach with a great system (Popovich and the Spurs) can enhance talents and overcome talent deficiencies all while consistently staying in the championship hunt. The Spurs have been starting T. Parker (under-rated all-star), Tim Duncan (under-rated, and limited, all-star), and Kawhi Leanord (rookie), Danny Green (young journeyman) and Boris Diaw (washed up, but intelligent and versatile big). Yeah, they have Manu (old, but still super-competitive), but they also have a roster of other really young guys who have drank the coach cool-aid. A team about "team"... that doesn't just pay lip service to the word team.
My point is that we'd be foolish to stay locked into our 3 star roster... and that we'd be smart to refocus our attention on converting our "assets" and bringing in pieces that contribute to a balanced inside/outside game who have the character to fully buy into the coaches system... even Woody's system.
