Trying to follow the logic. You think he would be a #1 WR on about 25 teams. (I agree with you.) But then you say he doesn't deserve to be paid like a top 10 WR? If there are only 7 teams with better #1 WR, this logic does not make sense.
FWIW, here are the top 7 guys in my list: Kupp, D. Adams, J. Jefferson, T. Hill, Chase, Diggs, AJ Brown. I think Higgins is right around #8 to #10, with guys like McLaurin, St. Brown, Lamb.
Now if you are saying "Bengals cannot afford two top 10 WR salaries", then we can discuss that. But you made it sound like he would be making an unreasonable demand to be paid like a top 10. Seems reasonable to me.
