I'm not trying to make an argument that Leno was good and shouldn't have been replaced. I'm making the argument that it's extremely risky to go from a starter to a rookie without any competition/depth.
Just to put those PFF numbers into context:
Leno 2020-2016 = 74.6, 58.6, 75.5, 78.7 and 70.1
Massie 2020-2016 = 72.6, 63.2, 71.8, 65.0 and 66.8
Ifedi 2020-2016 = 65 (guard), 56.2, 56.5, 51.7 and 51.3.
I've said this before, but you guys weren't happy with Leno and Massie. There's a real possibility that a rookie Jenkins and Ifedi are worse AND there's really nothing in terms of depth to help.
