Thielen is one of those guys you can get for nothing in Fantasy Football. Most white guys have never heard of him and the "projections" are always biased against him. He is at worst a #2 receiver that frequently puts up #1 numbers, yet you will have guys drafting #3's from other teams and unproven rookies. You'd think Welker/Edelman/Nelson/Decker would have enlightened the masses that white receivers can be great fantasy guys but it still seems like good white receivers never get their due.
Was just checking a prominent fantasy site's projections for Week 2, and they have Stefon Diggs as their 8th ranked receiver, and Thielen as 41st. It never fails to amaze how slow DWFs, including paid fantasy football "experts," are to recognize White talent at positions other than QB and TE even after they produce time and again (including White defensive players). And even at QB and TE the default mode is always to expect greatness from blacks while being leery toward Whites.
