What's your window of contention?
If it's 2 or 3 years what do you care?
And why don't we pay age? Generally speaking?
Well older players are less effective and more injury prone.
Murray is.... Today.... Less effective than Peterson AND more injury prone.
Why again would we want him over All Day?
Our window of contention is intended to be as long as Jason Garrett is the head coach.
2 or 3 years of paying a 29-year-old Adrian Peterson leaves us with a near 33-year-old running back who assuredly will continue to be a progress stopper for any other talent we acquire. We'll be bankrupt at the RB position by the time the contract ends, rather than in a good position to promote from within.
We don't pay age because look at what Jason Garrett has done. DeMarcus Ware's release shows the front office's mentality.
Your statement about effectiveness and "injury prone" is pure conjecture. Neither of those statements is supported by evidence that is worth examining in this situation. Murray has never played for the Minnesota Vikings and Peterson has never played for the Dallas Cowboys, so any comparisons are moot. "Injury prone" is a fun term that fans like to throw around as if they're an athletic trainer or an MD, but they arent. Another moot point.
Why would we want Murray over Peterson? (Also, cute that you refer to him as "All Day" -- confirmation bias has a way of torpedoing your own argument)
- Murray is younger.
- Murray knows the system.
- Murray knows this offensive line.
- Murray grew up in this program.
- Murray is a part of the chemistry of this team.
Just a few reasons that have further reaching implications when it comes to assembling something as complex as a football team. You don't just grab the guy rated 97 on Madden and plug him in and your team is better.
