The Jazz need wings more than they need 4's.
Maybe... DM, Exum, Allen, Royce, AB all play or can play the 2
Ingles, Royce, Crowder, Exum and maybe AB can all play the 3 - 2/3 are fairly interchangeable.
Favs, Crowder, Thabo, and Royce? can play the 4
I assume Kidd would be behind all the guys listed as 2s and 3s in the rotation. If we had an injury to Royce for example I think Crowder, Exum, AB and Allen get some minutes or redistribute minutes from 1/2 to 3.
If Crowder got hurt are we giving Thabo 25 min a night at PF? Would Royce take the remaining minutes? I think he could play some at 4 but others disagree. I think if we had an injury to Crowder or Thabo that another 4 would instantly be in the rotation. So rotation minutes are one injury away.
At 2/3 I think it would take multiple injuries before someone is in the rotation. Kidd or Royce maybe able to play the 4 - Or I guess they'd be the big wing in a 3 wing lineup is more accurate.
