They've got some guys listed as "fringe" that I like more than their "rotation":
Aaron Holiday
Willy Hernangomez
I can't imagine that Gordon takes a minimum deal; there are still teams with exceptions left, and the Clips can always resign him at a cheaper deal.
There's Grant, who I'd probably bring back at this point, assuming he doesn't get more than the MLE.
Then, I don't know. Cut Kornet and Champagnie, bring in a couple of vets. Biyombo? People seem high on Terence Davis, so maybe Brad can sign him? There are still a few solid options at SG/SF. But basically, a swing and a center, just like last year.
Timelord / Horford / (Biyombo)
Porzingis / Grant
Tatum / Hauser / Brissett
Brown / (Davis)
White / Brogdon / Pritchard
Walsh or Davidson get the 14th spot; the other gets the 15th if we fill it.
