I can see where a player would want to get max $$$ if that opportunity presents itself, although I think it has to be in the guarantee, not necessarily the overall dollars.
But is the (potentially) extra monies worth playing for the Jets, Jags, Dolphins??
Or (gasp!) the Loins or Bares?
I think playing for a perpetual All-World QB, strong teammates, in an environment like no other in the world has to count, as well.
