I dunno about the cap yet; but this is what Utah needs to prepare for:
Andre Drummond - 5/113
Al Horford - 4/113
Hassan - 4/98
Dwight Howard - 3/70
Bismack - 4/72
Joakim Noah - 4/72
Ian Mahinmi - 4/64
Tim Mozgov - 4/64
High - 4/90
Low 4/80
I doubt The Jazz would offer more than 4/80 unless their hand was forced on an offer sheet.
I think they'll go as high as 4/75 in the next couple weeks. I don't know if that gets it done - probably not.
Warning: I got blasted for the mere suggestion that Whiteside would help set Gobert's market value. The response was "he gets a max deal, period, Whiteside is irrelevant"
To me he is max or near max, the only 2 questions are (1) do they use their single 5-year designated player contract on Gobert, Hayward, or neither? (2) sign now or match next year? affording them some cap flexibility next year.
IDK if there is any advantage to extending him now other than helping his peace of mind.
