Well the counter to that is if you're playing an extra lineman unless he lines up eligible, and reports, we can't throw him the ball so it gives them an extra defender against the run because they know we're not throwing to Conner or whoever the 6th lineman is. In certain situations absolutely extra lineman on short yarsd for example all for it.
But in our base lineup IMO part of the reason we're so good at running the ball is simple math. Run game is typically 11 on 9 the offense only has 9 blockers the RB and QB don't block. But for us, because Kyler is such a good runner it's usually 10 on 9 because they have to account for Kyler. Reiman when he doesn't get a penalty is often the guy that springs the RB for a good gain.
I don't think he'll ever be a really good receiver I just don't think he's nimble enough to do that but he is a guy I hope we use more
