Average length of a NFL player
2015年1月10日Average length of a NFL player
In his conference call with Charger fans, NFL commissioner Roger Goodell said about the view that the average age of wholesale jerseys an NFL career is 3 years. Frequently, it is said that the average career is about 3.5 years. In fact, if a player makes an opening day roster, his career is very close to six yearsIf you are a first round draft choice, the average career is close to nine years. That 3.5 year average is really a misrepresentation.
That difference is semi curious.
Certainly, the NFL’s numbers are limited to players that started between 1993 2002 and players who made opening day rosters. Jason Lisk over at The Big Lead tried to check the NFL’s math, and came up with similar though not exact numbers over the same time period.
So instead of guessing where the NFLPA got their numbers, I decided to ask them. This is the information they provided me:
"The NFLPA ran a report on the average number of accrued seasons (6 games on a roster in a season) for NFL players as of the first game of the 2010 regular season, and the average is 3.54 accrued seasons. Here is the report:
Clearly, the NFL and the NFLPA are measuring two different things. Just observationally, in recent years, the trend has been against veterans on rosters and not just due to injuries. Younger players are cheaper. Vet minimums are higher than for younger players. Expensive players get cut if they don’t play to their contract or won’t agree to a pay decrease. If your team has expensive vets, younger players fill in.
These numbers don’t take into account the sizable number of players that do not make rosters. The term "accrued season" is relevant for players/teams because it can determine when a player is eligible for free agency. So a lot of the players on the above list have zero accrued seasons which pulls down the numbers.
So basically, what the sides are telling us is that they disagree on what they are measuring. Any math/football thoughts on these numbers or are you too disinterested to care?
More Annoying Labor Update Because You Aren’t Annoyed Enough.
It looks like cheap nfl jerseys the court ordered mediation between the NFL and players has adjourned until May 16th reportedly to accomodate Judge Arthur Boylan, the mediator’s schedule.
It’s quite possible that Judge Susan Nelson will rule whether to uphold the injunction against the lockout by then. On Monday, May 12th, Judge David Doty has a hearing set to determine damages in the TV rights, lockout war chest case. It’s sort of a non event. We’ve already known the opponents of the regular season for a long time. To predict how wins losses when we don’t even know the free agents and draft picks for the Texans much less their opponents is sort of a silly exercise.
And this year, it is such a tease. "Here’s our big unveiling of the schedule of the season that may not happen." Hoo. Ray.
Eyeballing the schedule, it looks like the early opponents are tough, but last year people wondered if the Texans could survive their early schedule and they did before the wheels fell off.
Schedule is fairly balanced between road and home.
Really, the most notable thing about the schedule is that it stinks for tailgating but is probably good for game prep stability: a bunch of noon games and only one evening game. If you can put your various states of agita, apathy and antipathy aside, here it is:
I tend to have (slightly) more sympathy for the players than the owners in this deal. However, if the NFLPA is computing a number as described and representing it as an length of a playing career then it is dishonest in the extreme.
Suppose you wanted to know average life expectancy, and you had a large room full of people. Would you simply ask everyone their age, divide by the number of people, and think that the result reflected life expectancy? Of course not. The result is average current age, not life expectancy. What the NFLPA is doing is the equivalent of getting all the players in a room, asking each how many seasons he has played, taking the average and calling it expected career length. Actually it just current average years of playing experience.
Maybe they better stick to being professional football players instead of amateur statisticians.
[Yes! I don’t much like the NFL method either because vets on rosters have significantly changed since 2002. I think these numbers are fairly meaningless. Steph]
