When I'm talking about "single-big", I don't simply mean the only big on the team. I think of it more as a versatile big who plays different roles depending on what the team needs in that possession. That means on ball, off ball, finishing and passing. Offensive run by elite guards don't need bigs to wear that many hats. They needs a guy who plays off them well, finish the opportunities they get and get boards. There's nothing wrong with those types of bigs, but the Spurs don't have the perimeter talent to allow their center to play such a focused role. But as I've talked about with Wemby, those parts of a center's skill-set a vital to an offense, which is why I think Bassey/Wembanyama should get some chances. Collins isn't perfect at playing that role either, but he's in the 72th percentile as a roll-man, for example. That's pretty good for a guy who's been shooting well from outside this year and has been passing well.
