9. Adam Thielen, WR, (Underrated)
There might not be a better combination of “great player on a great contract” than Minnesota Vikings wide receiver Adam Thielen. A savvy route-runner out of the slot position, Thielen finished with the fifth-most receiving yards in the NFL last year (1,276), and the eighth-most catches (91).
And yet, the Vikings have him on a contract in which his salary cap number in 2018 is only $6.1 million, which is an absolute steal. With new quarterback Kirk Cousins throwing passes in his direction, he could very well exceed his totals from 2017 and make a return trip to the Pro Bowl.
