I doubt Pope is really 6'1. Pope's weight will be a non-issue here.
If you shaved Pope down to 5-11 it doesn't make a difference. It's still a very rare body type in football.
In the last 20 years of the NFL combine:
- 17% of WR's 5-10 or smaller weighed 175 or less (26 out of 154)
- 2% of WR's 5-11 to 6-0 weighed 175 or less (6 out of 269)
I definitely agree with you and @OriginalCanesCanesCanes that Pope can be a really good college WR at 170 lbs.
But I also agree with @SouthernM that Pope at 170 lbs at his height is a very valid concern. It's rarely successful because it rarely even exists.
