a bit of a Twitter handbag fight last year or the year before.What happened was that a guy wrote a congratulatory comment about a player getting a “win” for other NFL players by signing a new record-breaking contract.I made the point in reply that Ross Pierschbacher Jersey , when a player signs an above-market contract, he hasn’t won a fight against the NFL owners, he’s simply taken money out of the pockets of his teammates, since the salary cap is a specific-sized pie; more for one player means less for the others.That guy kept arguing with me, which was fine.At one point, though, he suggested that I didn’t understand how the salary cap worked, and I realized that he thought I was stupid and wrong, while I thought the same of him.It was the first, and will probably be the last, time I ever get into an extended argument via Twitter.This past week, I wanted to write an article about something (I forget exactly what it was), and I wanted to begin the article with the same argument; that is, that the salary cap is a specific-sized pie, so more money for one player means less money for his teammates.As I started typing, I thought of the first objection I was likely to hear in the comments: teams don’t necessarily pay out the full salary cap.in cash this year.So, $31.1m in cash vs. $11.1m in cap space.The $20m difference is spread across the remaining 4 years of the contract — years in which his actual cash received will be less than his cap hit.When you put together all the players on all the teams across the league, the analysis from OTC says that teams are not paying out 95% of the cap, or even 100%, but that they are paying out more in cash payments to players than the scheduled salary cap limit — 101% of the cap, in fact — and no team is threatening the 89% minimum, with the Texans the lowest in the league, at nearly 93%.Because there’s so much smoke and mirrors in the management of salary cap, it’s easy to wonder if the CBA is accomplishing its goal of making sure that players are fairly treated and fairly paid.While Mark Twain famously pointed out that there are three great lies: “Lies Da’Ron Payne Jersey , damned lies, and statistics”, this particular statistic indicates to me that the CBA is working by making sure that, at least, the money that is supposed to be spent on players is actually being paid to them. In training camp last year, Washington was expecting rookie Derrius Guice to be its starting running back, and wasn’t even expecting Adrian Peterson to be on the team. But after Guice suffered a season-ending knee injury, Peterson single-handedly took over the running game and finished with 1,042 yards.So with Guice expected to be healthy and Peterson back this year, who’s going to be the starter?“That’s an interesting dilemma right there,” head coach Jay Gruden said. “Number one, Guice has got to get healthy. . . . He’s young, I’m sure it’ll be effortless for him to get back in shape, but still, we’re talking about a major knee injury for a running back. So, it’s something we have to really look at and make sure he’s 100 percent. And make sure he still runs with the same type of energy and charisma and effort he played with before the injury, because sometimes those injuries have an effect on you mentally. I don’t think it will with Derrius . . . but still, you never know.”Gruden said he thinks Peterson is capable of carrying the load again, but with Guice back he won’t have to.“Having AP back is nice,” Gruden said. “He rushed for over 1,000 yards. He’s a little bit older, but he doesn’t look it. He’s in great shape. Saw him the other day. It’s a great dilemma to have those two guys.”With Colt McCoy and Case Keenum battling for the starting quarterback job, Washington may need to hand off a lot. So Gruden hopes both of his running backs are ready.
