Good point on the financials. Eifert and Ertz are both low risk imo. But both are mid to late first round picks by many. If I had to go with a sure fire WR it would be Quinton Patton but again he seems like a late first rounder, early second. Depends where Colbert thinks he can get the value if he decides to remain put or trade down.
the only sure fire player that will likely be left at 17 is going to be an OG...and I don't mean an original gangsta.
