I admit not to watching Drummond much last year, for some reason the games of Detroit I saw he did not play/or did not play much. But IMO he is over hyped here, yes he has potential, so did Big Al, Gerald Green and hundreds others. Monroe on the other hand I did see, and the guy score, pass and rebound and has proven it. I'll take him over Drummond, maybe I'll be wrong in 3 years, but I'll take my chances.
First off I don't want to trade Rondo, but willing to. i would look for something like this:
Rondo, Wallace, Melo
for
Monroe, Knight and one of their expiring
Knight
AB (need to upgrade here)
Green
Sully/KO
Monroe
This is a good step in the right direction with a young team.
