Noise, according to CBS's Ben Gretch:
Given it was an island game, most people probably saw the Steelers run an offense heavy on jet motion and wildcat formations. Jaylen Samuels was a focal point, but not at the expense of James Conner, and both were in on several plays. The running back tandem led the team in a tie with eight targets each, and part of why they each caught all eight of their targets was that many were tip passes on motion plays. Samuels even wound up with a passing line of 3-for-3 for 31 yards, all three of which were tip passes to Conner.
Samuels' eight targets combined for negative-19 air yards, meaning on average he caught the ball 2.4 yards behind the line of scrimmage. Conner's touchdown reception came on a sprint out where he was out in a short curl route before he showed off plenty of after-the-catch ability for the score, but even with some positive air yards on that play his air yards total for the day was negative-9 yards.
In fact, while Mason Rudolph finished with what looks like a sterling passing line of 24-for-28 for 229 yards and two scores, he totaled just 95 air yards on the night for an aDOT of 3.4, which is tiny for a quarterback and would have been even lower if not for a third quarter downfield shot to Diontae Johnson that went for a 43-yard touchdown.
It was a gimmicky offense and it worked perfectly against the Bengals, but whether they will continue with that offense to the same degree next week is very much up in the air. These types of moves are often one-game switches, and while we might see some of this incorporated going forward, I expect a more traditional offense next week.
I would have a hard time starting Samuels in Week 5, despite his productivity, unless I was very thin at RB. I counted seven direct snaps he took in the wildcat, including his rushing touchdown, and the passing stats from that formation added to his Fantasy total. If I had to guess, I'd expect more like two or three direct snaps next week. Then there's the issue of his receiving role, and while he did catch a few passes on dumpoffs that weren't designed tip passes, there's no question the scheme helped boost his receiving line to eight catches and 57 yards. He'd be an upside play on the hope he's still incorporated in similarly creative ways, but it's always a bit thin to trust gimmicky production to carry over.
