Players often cite hometown, college, or highschool. The citation has nothing to do with the care or lack of care for their college. Greer could mean nothing or something by it. I think you are over-analyzing it. He may just be giving some love to his hometown, which is never represented. I would not be offended if the great one "THE PEYTON MANNING" cited his hometown periodically also. This does not show a lack of care for either the school or his hometown. In philosophical terms this is the called the fallacy of false dichotomy. Either Greer mentions TN and is a fan or mentions his hometown and is not a fan. You are placing to things at odds with each other that are not necessarily at odds with each other. Look at it in a syllogism:
1) All players must mention there college during the game or they are haters of their school
2) Greer mentioned Jackson,Tn as his hometown
3) Therefore Greer is a hater of his College
#1 is not necessarily true and therefore conclusion #3 is false. There are multiple other options that could occur and Greer still be the most adamant VFL. You also could use the same reasoning in regards to hometown. If a player mentions his college, he therefore is not a fan of his hometown. Both premises are fallcies. Sorry to go philosophical, but I think this thread is silly.
