Actually, it illustrates an interesting point about the psychology of fandom - fans with inferiority complexes about their teams tend to venerate their players and coaches by giving them nicknames. In a sense, it is a process of mythologization, turning the ordinary man (Richard Rodriguez, Greg Robinson, Will Campbell, Tate Forcier, Denard Robinson) into an extraordinary (if not quite superhuman) character or persona (RichRod, GRob, Bill Will, TForce/4CA, Shoelaces). In the minds of the fans, "Tate Forcier" sounds rather dull and pedestrian, maybe even a little bit wimpy ... while "TForce" sounds unstoppable, all-be-it in a rather cartoonish sort of way. But hey, if your team doesn't have any real superheroes, then I guess that you need to invent some.
Incidentally, I first noticed this phenomenon with the mid-90's Seattle Mariner teams who won a ton of games but couldn't do anything in the playoffs - remember Junior, ARod, The Big Unit, and Mr. Clean? The Mariner fans always had that expansion team inferiority complex, and it got worse when the team started to become respectable in 1995.
