Every team needs at least a dominant 2 players. You can't have a winning team with a bunch of role player talent (sans Harden).
No, you don't build a business around one employee but the CEO is the guy that will take charge in growing the business. Can't have a successful business without a business savy CEO.
How about a crew of GELLIN role-players that co-exist so well they become a lineup of Star-Role-Players.... The 2004 Championship Pistons or the Seattle Super Sonics aka the young OKC Thunder.
