Remember the days of Troy Brown or Julian Edelman playing wide receiver and cornerback? How about Mike Vrabel being a linebacker and tight end catching touchdown passes from Tom Brady?
Bill Belichick has always valued versatile players with a particular set of skills, and Abram Smith fits that mold.
Smith is an interesting player because he is a former running back, that turned to linebacker, and then turned back to running back again. He should be able to make a 53-man roster with his position versatility. At the very least, he should be able to contribute on special teams.
