Cute.
I'll admit I was drunk when I started this thread so perhaps this is my fault because I just said "snaps" instead of "snaps at QB". But I sorta thought it was implied when I'm comparing him to a QB. Obviously Hill doesn't turn the ball over nearly as much if you count all the snaps he has as the second TE or fourth WR. But you've included those here. And really you're using interceptions + fumbles instead of total turnovers (this would be interceptions + fumbles LOST). But that's fair I suppose, fumbling is still bad regardless of if it results in a turnover.
It seems a little hard to piece together without paying some website to look at more in-depth stats, but from what I can tell Hill lines up at QB somewhere between 14% and 17% of the time on offense. That's where he turns it over. Fumbling the snap, rushing from the QB position, or throwing a pick.
Going back three years he's had 550 offensive snaps, so likely somewhere between 77 and 94 snaps at QB. Taking that into consideration Hill fumbles or throws a pick somewhere between 1/19 and 1/24 snaps (he has three fumbles and one pick since 2018). Worse than Jameis. And actually from what I can tell Jameis is closer to 1/29 snaps per fumble or interception than the 1/36 you show.
If you want to talk strictly interceptions per attempt, Hill has thrown 1 pick in his 18 attempts. Jameis would be at 1 pick per 22 attempts. Small sample size for Hill there though so maybe it's not completely fair. Then again, we don't have anything else to go off of other than...well.....you know....the only actual passing stats that exist for Hill.
