There are a few stats that I think show something quite telling about the difference between Bagent and Fields and why some (extremely dumb people) might have gotten enamored with Bagent.
Pro-Football-Reference keeps a stat called 'Success %' - it measures how often a QB makes a play on 1st down that gets at least 40% of the yardage needed on 1st down, 60% of the yardage needed on 2nd down, and 100% of yardage for 3rd and 4th down. Bagent has a 52.2% success percentage, Fields, in contrast, has a 38.7%. That's really bad. A good QB seems to hover around 50%, give or take a few percentage points. Bagent's 52.2% success percentage is actually up there with the top line QBs ---of course I'm not saying he's playing like a top line QB, I'm drawing a distinction between the two---
Justin Fields' sack per drop back percentage? 12.9%. Tyson Bagent's? 4.3%. This is playing behind the same damn line. Tyson Bagent's completion percentage is 6% higher than Fields.
A 14% difference in successful plays is a huge differential. That's a huge chunk of opportunities where Fields is not doing the job while this undrafted kid is. That kid is also turning the ball over faster than hotcakes, but he's facilitating the functioning of an offense that is, when its not turning the ball over lol, significantly more efficient than Fields was. Now, that may come down to a bunch of factors, it could come down to coaching, the offensive line finally gelling, improvements in the run game, etc. But, well, in stark numbers, there's a huge failing right there.
