Necessity is the mother of invention (and I am a pun machine), so let's take a look at a few I happen to know about:
(You might remember her from when she got up in KG's grill on the sideline last season and LeBron almost went apeshit on her)
Joakim Noah's mom
Allen Iversons mom (old school)
I did some google digging but sadly, didn't come up with anything else worth posting. However, I will assure you that there will be a hot wives/girlfriends post coming at some point... Jesus, there are some ridiculous chicks out there.
Anybody think of a sports MILF I missed?
