The NFL is all about what you've done for me lately.
Winning a Super Bowl will only carry you so far in a city like New York if you don't validate it with at least a couple playoff wins.
And earning a huge contract for being perceived as one of the elite defensive players will only enrage fans if they don't see effort.
The current structure of the NFL is set up to pay rookies an obscene amount of money in their signing bonus and to give mega contracts to proven veterans.
The dilemma teams run into is rookies may not warrant the investment and veterans may have peaked way too early for the price tag they demanded.
The five players on this list have cashed a big paycheck and need to prove they are actually worthy of the money.
