First off, there's no reason for distinction between locks and near-locks. Zach Wilson isn't getting cut, but neither is Daniel Sorenson, Takitaki, Jamaal...or Michael Davis. Davis just signed a big contract this offseason and is penciled in as the Chargers #1 corner. He could get burned every play of preseason and still be on a roster.
On the other side, Bushman is currently listed as TE5 for the Raiders according to OurLads. I'd like him to be in a comfortable spot, but I just don't know that it's the case.
Again though, the distinction between near-lock, comfortable, and competitive is ... unclear.
I'd rework it in simpler categories. Safe, Questionable, Unlikely. If you want you can break Questionable into two groups depending on which side of the line they fall on.
