Speaking of gimmicky offensive ideas, how about that screen and roll play with Fox and Holmes on that last play. They practically set the pick all the way at the mid court line, haha. That will give Fox a running start every time.
Harden gets way high picks too. It could be worth a shot but obviously teams will zone off since it's fox but even so that could give the offense that buffer on the sides Vlad was talking about with Bagley running point.
For the love of god please play Hassan more. He makes a big difference out there. He looks awkward on offense but he's got a literal large presence out there.
