This may be just me, but I wouldn't trade Crowder alone for Monroe. It may not be entirely his fault, but teams with Monroe seem to underperform. IMO he's a one-way offensive player with no upside. He is what he is. Crowder is also on a great contract while Monroe will make $17 million this season and has a $17 million option for the following year that he will likely opt out of and seek an expensive long term contract.
