If you owned him would you accept a trade for Monroe straight up? A Pau Gasol anywhere near last year's level would be huge for my team but I don't know if I should take the risk that he won't pick it up.
gasol is hard to predict because the lakers are such a mess right now. monroe is the more consistent option and has a bit more upside. i would personally take monroe over gasol bc even if gasol bounces back i don't envision him being much better than what monroe will give you anyways.
