I'd sign Marquis right this second. He can only be offered a small raise on the LLE, so we wouldn't be paying him anything crazy. And at that money, it'd be fine if he was the 4th or even 5th wing.
If Nate is going to take something sensible, I'd take him back right now too.
I'd still be pursuing upgrades at the wing spot, but we might as well cover our butts right now.
As for Scal, I'd wait and see where we are in a month. We could use more of a true center than a PF right now.
