A Derrick Rose lob to me
And watch and see I alley-oop it properly

from Lupe Fiasco – Put Em Up Lyrics on Rap Genius

Meaning

Lupe is from Chicago so it’s only natural that he mentions the best player on the Bulls, whom once he mentioned is the best player in the league:

Continuing on his last line, telling you to “put ‘em up”, like Derrick Rose throwing an alley-oop, a pass that is lobbed in a rising form for the receiving player to catch in mid-air and dunk it.

Lupe is saying to pass it up to him and he’ll show you how to finish it.
