OK folks, there are several sell-high guys out there, so let's roll through some. And if you're in a league where no one trades, that's unfortunate. But maybe you can shake some sense into your opponents by dangling a little talent and seeing who bites.
And I won't mention some of the obvious players, like Zeke Elliott or Amari Cooper or CeeDee Lamb. The Cowboys are in trouble, and no one's paying what those guys were worth 10 days ago. I'm more interested in players who have reached peak or near-peak value.
At QB, Ryan Tannehill is #6 in scoring and #4 in passer rating despite missing one or more key receiving weapons most weeks. That said, I don't like his upcoming schedule (Steelers, Bengals, Bears, Ravens, Colts twice). That's not to say the veteran can't muster a few solid outings these next weeks weeks. But in all likelihood he's peaked, and a non top-10 finish is likely. To put it more bluntly, the Steelers, Bears, and Colts are all top-3 in opposing QB rating, while the Bengals and Ravens aren't far behind. I'll be even blunter: four of his first five opponents are bottom-6 in QB rating. He is a screaming sell.
At RB, it's James Robinson, James Robinson, James Robinson. I warned against him this summer, then ate my words when he quickly became a rock-solid RB1. But with fumbles in back-to-back weeks (despite only losing one) after fumbling six times his senior year of college, Robinson could go from hero to streamer at any time. Look, we're always taking calculated risks, and I could be wrong about Robinson yet again. But if you can cash out at or near his RB-7 production value, do it and move on.
At WR, D.K. Metcalf is the 8th highest scoring WR and is on pace for only 70 catches. The last time a top-8 WR had fewer receptions was Jordy Nelson (68) in 2011. I'm not saying Metcalf isn't an incredible fantasy asset. I am saying he's done more per reception than nearly any other player going back many years. Assuming he doesn't suddenly become a high-targeted option, he's a strong bet to regress. If you can get full value for him now (top 7-9 WR), play the percentages and take it.
Finally, Robert Tonyan became a TE1 with Davante Adams sidelined. He's now the 7th-ranked tight end and is on his way back down with Adams back. That's not to say Tonyan's worthless; he's a legit talent and potential #4 option in this offense. But he doesn't catch enough balls to be more than a TD-dependent streamer.
