1. Sheldon Richardson DE Mizzou .... The Texans are pretty thin and old up front . Crick is ok and Jamison is hurt . 2. Kevin Minter LB LSU ... I'm not sold on Sharpton and James and Dobbins are older . Oh yeah Cushing got hurt . 3. Jesse Williams DL Alabama ... Cody is a FA and Earl is an OK back up . May be able to play DE . 4. Quanterus Smith OLB Western Kentucky .... I expect Barwin to leave . My two cents on where I think the problems are that have to addressed .
