Former Rams general manager Charley Armey doesn't believe that the team should considered trading the second overall pick in this month's NFL Draft. "The No. 1 cardinal rule for me absolutely, without question, is do not trade out of an impact position," Armey said. "Because there's only a few impact players. Some years I've been in the draft, it was only around six impact players. The year Orlando Pace was in the draft (1997), there was only about six. The year we took Torry Holt (1999), there was about 13."
