past considerations from earlier Mike Montler trade

Denver acquired 1981 twelfth round pick (probably #321-Mandel Robinson); past considerations from earlier Mike Montler trade from Detroit Lions for 1980 eighth round pick (#196-Ken Walter). This was primarily a draft-position exchange, with Denver reshaping its pick stack rather than adding an established player. The grades stay conservative because the historical value depends on how the selected players developed after the swap.
