I just think there's bigger things to worry about right this second. Scal would be OK at the minimum, but we already have 9 players under contract, plus the Lafayette, Gaffney, and Edren (though only partly guaranteed I believe). That's 12 possible players. We at least need a legit 5 (not Scal) to stand in for Perk and at least one, if not two, other wings. That's 14 or 15 players right there, or 11-12 if you anticipate on us cutting all three of the Summer Leaguers.
Plus, if we do end up trading Sheed's deal, we may have to take back more players than we take (a 1 for 2, or 2 for 3 type deal). If that was the case, Danny could end up having to cut Scal after he signed him.
So I think it's possible, but I think Danny wants to see how things play out before he makes any calls. Scal would certainly be an OK 5th big until Perk comes back when he'd become the 6th (which was his role this year).
