The #Texans have reached a contract agreement with third-round pick Sam Montgomery.— Tania Ganguli (@taniaganguli) May 23, 2013
As Ganguli points out here, this news leaves only DeAndre Hopkins, D.J. Swearinger, and Brennan Williams unsigned from Houston's 2013 draft class.
All that's left to see is if Sonic Sam locks down that starting OLB gig like TDC predicted.
