You cannot just pick in choose when you what matters when comparing players, you cannot base Brady and Manning on SBs and then turn around and base the Edelman and Welker comparison on stats. That is just using things when convenient.
There is a lot of convenience in the arguments on this board though, Bruins29 is in one thread lobbying for Amendola based on his last few games (which is fine), but then he is in this thread suggesting people jump to the hype for players to quickly when they do well. Personally, I would just appreciate some consistency.
