Not a fan of that move. If Richardson falls to them at 17, they should, as I read elsewhere, make light speed to the podium. But there is enough running back talent that I'd rather see them draft a solid OG and a lesser RB than trade the opportunity to improve the line in lieu of a running back that is going to need that line.
Actually, if Richardson fell to them at 17, what I wouldn't mind seeing is them trade down and get both of New England's First round picks as well as one of their second rounders. Then with the five picks in the first two rounds draft CB, DL, OG, OG, RB in no particular order.
