Trading Lee will be a big mistake, no pun intended.
And why is that?
Maybe because he's playing well. Maybe because he's the only capable guard defender on the bench, maybe because you're one injury away from having a big hole in the guard rotation, maybe because Terry has shown time and time again that he's being misused and doesn't fit well with our personnel?
We want a big, that's cool, but I'd be very wary of getting it at the expense of Lee if with no appropriate replacement in mind.
Reality is that if a big trade happens, then Lee is probably part of the equation because he's an attractive asset, which is why I'm more in favor of a small trade in which you can just move someone like Bass, maybe include Barbosa or Melo, or a pick and get a someone who better fits with our bigs.
That said, I'm not sweating it, once Wilcox returns the rotation should look more solid, and with a free-agent pick-up who can give us some decent spot minutes at the center, something better than what Collins provides, and we should be good.
But I'm quite certain that Lee will be key to have success this year. Doc has him in a very limited role at the moment, but even that is very useful... there's a reason why our bench has been playing well in the last few games, and he's been a big part of it with his defensive presence.
