Not to mention Kanter might suck. So might Favors. Sap's ceiling might be topped out. Al might prove his individual talents are more detrimental to team play than they're worth.
The crazy thing is assuming anyone is a bedrock, or the future, and planning that way. You put the best guys on the floor every night. If Kanter or Favors are so good, they'll force their way onto the floor. You don't assume NOW that they're going to be studs and put proven players out to pasture just to get that assumption going.
Anyway you gotta make choices, after 3-4 years from now, we cant keep all the guys we have right now. We dont have a guarantee Kanter or Favors will be very good players, but it is a high possiblity that they will be. And it is not a bad idea to start guys who have potential right now if we are a rebuilding team. If you think like that, then it was a bad idea that Oklahoma gave all the responsibility to Durant and Westbrook as soon as they get drafted
