Pre-draft news conferences featuring NFL general managers provide a good opportunity to ask about issues beyond the draft.I was interested Wednesday in hearing the San Francisco 49ers' Trent Baalke explain what the team envisioned for Glenn Dorsey, the defensive lineman his team added in free agency. Dorsey, the fifth player chosen in the 2008 draft, appeared miscast at defensive end in the 3-4 scheme Kansas City adopted early in Dorsey's career.
