Glen continues to impress me. For every time I get annoyed with him for getting blocked under the basket or having his shot altered on a layup, he makes up for it twofold with a big jumper or drive to the hoop in crunch time. I agree with the general sentiment here: for the money, the skill, and his general acceptance of his role on the bench, he's a good fit.
That said, I wouldn't be completely opposed to trading him. Why? Because he's really our only tradeable asset right now. He's cheap, an expiring deal, and while good, probably not a huge part of the rebuilding process (he's still not good enough to start on a contender).
Now I'd still like to trade Wallace's deal. However, if Wallace changes his mind (unlikely, but more likely with Wallace than others since he's crazy), trading BBD might be the only way to upgrade the wing spot. Or, if a perspective trade partner for Wallace needs a sweetener, and would give us a good 3 and 5 in return, I'd be down with trading him too.
