I too love Sheldon Richardson, though I severely doubt he'll make it out of the top 15, maybe not even out of the top 10.
I'm a really big fan of William Gholston. 6'7" 280 lbs who is really strong with an attitude. Could probably get him with our 3rd round pick. He has the body to put on weight too. Long long arms as well.
Geno Smith is just as smart and just as good of a passer as RG3-Sac
