Just like the headline says who are your least favorite to put it nicely, current or former NFL players just give two 3 names. Mine would be the following:
Emmit Smith: I love in Pensacola where he is originally from, he is an ass to the people from his hometown. So much so he tryed to charge a 9 year old for an autograph. (btw Roy Jones Jr. is from here also, and is one of the nicest guys you'd ever meet)
Brett Favre: Plain and simple his ego and that hes an a******.
So personally i dotn care for these two however both are(were) great football players.
