I wish I had access to how many snaps he lined up in the backfield, but it looked like 1 out of every 10 or so snaps. He's bigger, with bigger hands, though shorter arms, than Kittle. From this class, only AJ Barner had a better blocking grade than Sinnott.
Imo he was less effective than he will be in the NFL, because opposing defenses knew he was K State's best offensive player, and he was typically bracketed. K State's QB also really struggled to throw the ball on time, so you see a lot of reps where Sinnott is open - just not when the QB finally gets him the ball.
Imo his FB usage was more about Kansas State trying to free him up, because defenses were focused on him, and trying to vary the offense, because they didn't have a lot of talent, than it was about him being a FB. I also think it speaks to his athleticism and versatility.
I think he's kind of between LaPorta and Kraft from the '23 draft - 2 of the 3 guys I had in the top tier last year.
