Essentially, yards per target is just the opposite end of yards per attempt. If yards per attempt is a good indicator of quality, then logically speaking, yards per target must likewise be a good indicator of quality. Now, there might be other factors out there that we can use to adjust yards per target to make it even better, but the basic stat itself correlates very well to yards per target, a stat I know you're a fan of.
This is my problem, and I actually fell into the same trap at first. But YPT is not the mirror of YPA, despite the mathematical certainty that they must equal each other. It's a classic Simpson's Paradox issue.Assume a team with two WRs -- neither is a deep threat or possession receiver, rather, both are somewhere in the middle. WRA is much better than WRB, however. When WRA is open, he gets every pass. When WRB is open, he gets every pass. When both WR are covered, WRA gets the target 90% of the time, because he's much better than WRB.On 50 passes, WRB is open, and converts 36 of those passes into receptions for 540 yards. On 50 passes, WRA is open, and converts all 50 into receptions for 850 yards. So far, it's clear that WRA is better. He's averaging 17 YPR, has a 100% catch/target ratio, and is averaging 17 YPT. WRB is averaging 15 YPR, has a 72% catch/target ratio, and is averaging 10.8 YPT. A blowout for WRA, on all counts. On 100 passes, both WR are covered. The QB throws 10 times to WRB, who can't log a single reception. The QB throws 90 times to WRA, who records 20 receptions for 200 yards. WRB stunk, while WRA was merely bad. Once again, clear advantage to WRA.Now look at the season totals. WRA has a 15 YPR average, a 50% catch/target ratio and is averaging 7YPT. WRB has a 15 YPR average, a 60% catch/target ratio and is averaging 9YPT. So WRB has much better catch/target and yards/target ratios despite clearly being the inferior receiver. The only sign we have that WRB is the inferior receiver, of course, is that he saw 90 fewer targets. So no, yards per pass attempt is not the same thing as yards per target. There's a much smaller threat of a Simpson's Paradox problem there (a threat exists to be sure, but it's on a much smaller level). The fact that a WR got a target is a very telling thing, because there are usually 3 or 4 other players on the field that could have gotten one.
