Yeah, this Detroit situation is a mess. The truth is they are going to lose him for absolutely nothing next year if they don't lock him up now. They could always trade Josh Smith, but they are at the point where they would hope to give him away now.
I know this isn't a popular option amongst people who think teams absolutely won't trade big men, but trading Drummond could probably prove to be the best thing for them. Monroe and Smith actually complement each other quite well as a C/PF combo and I imagine they could get quite the haul for Drummond. From us alone, they could probably get Rondo, Green, and a pick. That would allow for them to balance out their roster, be competitive now, and most importantly maximize all of their assets.
That has to be better than Monroe simply walking and still sucking at the PG and SF positions, right?
