What you’re failing to acknowledge is he’s produced at this level his entire career. It’s not a small sample size. The injury and suspension limited his games played the last 2 years, but his production while on the field remained elite. It’s not an anomaly, it’s how he’s always produced.
If you wanted to argue that he’s at the age where WR’s tend to start to decline and the chance of regression is high, you’d have a point. That’s the risk of investing in a 32 year old WR. It’s possible he starts to slip. It’s also possible he keeps producing at the same level.
I for one like the fact that his hands, size, and craftiness are the key factors to his success. He’s never been a burner so he’s less reliant on skills that are likely to fall off at this age. At least that’s how I see it.
There is risk involved, but I think it’s far outweighed by the potential reward of an absolutely monster season as our #2 WR.
