$ If 30 is the Magic Age for RBs, then what is it for WRs?
Thursday, September 10th, 2009- Theory:
You’ve all heard the old saying, “Once a running back turns 30, his production goes downhill.” That statement has been debated among fantasy (and reality) stat-geeks for years. But what I have always wondered was, “Is there a so called ‘magic age’ when a wide receiver’s production starts to dip. It surely can’t be 30 because the GOAT Jerry Rice put up better numbers in his thirties than his twenties. But it wasn’t just Rice who had success late in his career as guys like Charlie Joiner, Mushin Muhammad, and Steve Largent were first team All-Pros while in their thirties. But I figured there must be some age where the legs get a little slower or the vertical drops a couple of inches. There’s got to be some age where there is a noticeable difference in a receiver’s abilities. To help me find this ‘magical age’, I decided to conduct a study using the top receivers in NFL history.
- Research:
My original sample size consisted of every wide receiver who had reached 10,000 receiving yards in their career. Then I rationalized that this magic age is somewhere in the mid-thirties so I removed all players who retired before playing a season at the age of 36 or who were still active and had not yet reached their 36th birthday (Owens, Moss, Holt, Muhammad, Mason). That left me with 14 players who met the above requirements. The 14 players do not include Rice as he only played in two games when he was 35 due to a knee injury so his production would have distorted the results. Likewise, Marvin Harrison only played five games when he was 35 and Harold Jackson played one game at 36 so they also were not included.
- Results:
What I found was surprising, not because of what the age is, but rather how steep a drop-off there is at the age. I added up the 14 players’ receiving yards and separated them into three sets: production at ages 34, 35, and 36. If a player had a birthday during the regular season then that entire season was calculated for the age in which he turned. For example, Cris Carter turned 36 on November 25, 2001, so the 2001 season is counted as his season at age 36.
For the 14 players, the average receiving yards they had at age 34 was 998, at age 35 was 933, and at age 36 was 665.
That amounts to a 6.5% decline in production from 34 to 35, or 65 yards. From 35 to 36, there was a 28.7% drop in production, or 268 yards. You’re probably thinking, “I bet those players played in more games when they were 34 than at 35 and more at 35 than at 36.” I thought that too after I did all the calculations. Then I went back and added up the number of games played at each age. The number actually increased at each age: 204 played at 34, 208 played at 35, and 216 played at 36.
- Conclusion:
The numbers don’t lie-receivers go downhill in a hurry whenever they turn 36. There were eight 1000-yard seasons at age 35 from those 14 players. There were only three 1000-yard seasons at age 36, but not from just the 14, but from every receiver in NFL history. That’s right-only Jerry Rice, Joey Galloway, and Jimmy Smith have had 1000 yard seasons at the age of 36. Those three, especially Rice, were outliers for the wide receiver position just as Curtis Martin and John Riggins were outliers for 30+ year old running backs.
So what does this mean for your fantasy team? It means you would be better served to stay away from guys like Muhammad (36), Bobby Engram (36), Isaac Bruce (37), and even Terrell Owens who turns 36 in December. Owens’ decline started last year when his yards dropped by over 300 from the year before. I don’t think there will be a decline that steep this season but I do think there will be a decline nonetheless. There are numerous factors already working against him. First he’s playing with a QB who’s not a Hall-of-Famer like Steve Young or has not been to 11 Pro Bowls like Garcia, McNabb, and Romo have been too combined. Next, he’s not the clear-cut #1 receiver on his team for the first time since he was in San Francisco. Finally, he has that nagging toe injury which could linger throughout the season. If that toe isn’t completely healthy, then he’ll have trouble cutting on it and creating separation from cornerbacks.
Who knows if TO is the next outlier? I don’t and I never would have guessed that Jimmy Smith would have been one. The draft is your call; you can pick whomever you want. Owens, or any of the other 36+ crowd, could be the next Jerry Rice and be a 1000 yard receiver at age 40. Or, they could lose the battle with Father Time and make you wish that you could re-draft. Those are decisions that every fantasy owner, including myself, are faced with. Just before you think that we’ve got it bad; imagine being a GM and dealing with these decisions in real life….makes me kind of thankful that it’s only fantasy.
