I hate when TDs are pulled out in stats arguments, for any players.
For one, TDs are a small sample size stat. There's a lot of variance.
In addition, they're sort of a team stat. A good offense will create more opportunities for all of its skill players to score TDs. The KC Chiefs WR will have more chances to score TDs than the Saints WR, no matter who you plug in there.
Yards per route run is a lot better metric. WRs run a lot of patterns, so there's a big sample, and their yardage has a pretty direct correlation with their individual success (if they are beating their man, chances are they will get the ball, and if they aren't, they won't).
YPRR isn't perfect. Football is like Confounding Variables, The Sport because everything interlocks super heavily. But it's better than just box score TDs.
CeeDee is 4th in the league in YPRR, behind JSN, Puka Nacua, and Stefon Diggs. He's just ahead of Amon-Ra St. Brown and Ja'Marr Chase. So Lamb is doing just fine.
