He is 62 percent completion. Some people clamoring for Fields at 61 percent. There is a mechanical issue with most incomplete passes. By every QB.
Not clamoring for Fields, but your argument makes a case to get him. It also brings to mind some questions about both he and Kenny.
IF Kenny and Fields have comparable completion percentages, and, "IF" most incompletions are mechanical issues; by every QB, then "IF" you can fix the mechanical issues of Fields and Kenny, you should go with the QB who has more "upside". Fields has a better arm, is a better runner, a better athlete overall. So, "IF" you can fix the mechanical issues of both QBs, Fields would offer you more at the QB position than Kenny.
-EXCEPT
1. Fields is more prone to turnovers than Kenny. The question is, is that also because Kenny has been handicapped? Does he throw more INTs if he's "let loose"? I guess we'll see.
2. We're assuming that KP8's mechanical issues (and Fields' should they get him) are fixable. Maybe they aren't. Maybe neither of them can or, is willing to fix their issues.
3. Bailing from the pocket is not a mechanical issue. It's a processing issue. QBs bail when they feel pressure or think there will be pressure. Too often, KP8 has bailed when he "thinks" there is going to be pressure; which, if he had stayed in the pocket, wouldn't have arrived.
I don't know what the Steelers are going to do, or even should do regarding the QB position. We'll see. I do know that I'm tired of the QB play we've seen over the last few years and it needs to get better by whatever means.
