Peter King led off his weekly MMQB column this morning with some talk about LeSean McCoy's new contract. He notes that with all big, long term deals with running backs, there's risk. There's countless of examples of really good backs who failed to live up to their big deals.
However, as King notes, really none of these guys got their big deal at 23 years old.
The most amazing thing about McCoy is not how precocious he's been in his first three seasons, averaging 1,414 yards from scrimmage a season. It's that he's 23. The Eagles signed him to a five-year deal Thursday, and five-year deals for running backs are always dangerous. But Steven Jackson will take his first carry of this season for St. Louis at age 29, and Michael Turner is 30, and both could easily finish in the top five in the league in rushing this year. McCoy will take the last carry of this contract at age 28.
