When it comes to building a basketball team, there are basically three types of players you want on your team:
1. Go-to guys - These are your superstars, the core of your team. Without these guys, there wouldn't be anything to build around.
2. Proven veterans - You know what you're going to get from these players. They may not be as athletic as the days of their youth, but you rely on them to provide some sort of steady role on your team.
3. Youth with potential - Young guys who have athleticism, energy, or above all, potential. Sometimes these players are expected to provide a spark off the bench. Sometimes they get heavy minutes and are billed as "the future of the team." Or sometimes they sit on the sidelines as they develop.
In the last couple of years, the Spurs have tried to build championship teams largely with numbers 1 and 2. Yes, they've relied somewhat heavily on young guys at times (see Parker, Tony and Jackson, Stephen), but for the most part their role players have fit into category #2 (Kerr, Barry, Finley, etc.). And yes, they've occasionally signed younger guys, but you wonder how much they really staked in their development (Butler, Marks, Washington, etc.).
Now, however, the 12-man roster for 2008 is expected to be a pretty even balance of all three categories. I could break it down by position and show you that they have at least one of each in the PG, wing, and big man rotations, but for the sake of brevity, here's the synopsis:
1. Go-to guys
Parker, Ginobili, Duncan
2. Proven veterans
Vaughn, Finley, Bowen, Oberto, Thomas
3. Youth with potential
Hill, Mason, Udoka (still developing despite age), Mahinmi, Bonner, (Tolliver)
(yes, I know there are 13 guys on my "12-man" roster; most likely out: Hill or Vaughn)
Obviously relying heavily on category #3 is much riskier than going with proven experience, but there's no doubt the Spurs needed to get younger, and at least they've done it with a sense of balance.
