If you don’t play fantasy football, you probably have no idea what this title means. Of course, it’s 2013, so if you don’t play fantasy football, you’re now the oddball. “PPR” stands for points per reception. About half of all fantasy leagues do not give any points for receptions, while the other half includes some sort of PPR format. And while the value of every player is dependent on each league’s scoring system, few players see their value fluctuate between scoring systems quite like Wes Welker. Or, at least, that’s how it seems. Is there a way to measure this effect?

First, a review of Welker’s numbers since he joined the Patriots:

Welker doesn’t get many touchdowns, and while he has respectable yardage totals, he is only exceptional when it comes to piling up receptions. Welker has 672 receptions over the last six seasons, easily the most in the NFL (in fact, it’s the most ever over any six-year stretch). Brandon Marshall (592) and Reggie Wayne (578) are the only two players even within 100 catches of Welker. Over that same time frame, he ranks 4th in receiving yards, but only tied for 17th in receiving touchdowns.

So how can we measure how much more valuable Welker is in PPR-leagues than non-PPR leagues? One way is to use VBD, which is a measure of how much value a player provided over the worst starter (or some other baseline). For example, Welker scored 173 fantasy points and ranked as WR12 in non-PPR leagues last season. If you are in a start-three wide receiver league, the worst starter would be WR36, who scored 111 fantasy points. That means Welker provided 62 points of VBD.
