While some guys undoubtedly will sit:
• Cortez had no intention of missing most of 2016-17 to injury at the time he decided to transfer in, and he probably thought (knew) he controlled his own destiny if any other highly talented guys at his weight signed on thereafter.
• Keener is transferring in for a single season -- a season where 133 was a need weight for PSU. He won't be sitting unless Cortez is able to cut back down to 133.
• No indications thus far that N. Lee will be riding any pine during his career (barring injury, of course).
• TBD whether Manville will need to sit more than a year, if at all.
I think the vast majority of D1 wrestlers have at least a touch of self-delusion, with many having full-blown self-delusion. It's just the mindframe adopted in the sport -- no room for doubt in the mind if one is to succeed.
As to your last sentence, I fully agree. #BubbaJenkins
