These are the top offensive players who could go before Dallas picks:
QBs - Lawrence, Wilson, Fields and Lance (some team is going to fall in love with him especially with no Combine this year). (NY Jets, Jaguars, Bears, Steelers, Dolphins (yes, you read it right), Falcons, Lions, Panthers - all could make a play for one of these quarterbacks.)
WR - Smith and Chase (Philly and Miami)
OT - Sewell (Dolphins, Bengals or any other team if he slips).
That leaves one of the top defensive prospects (Farley, Surtain and Parsons) available to us.
