If the Lions are serious about finding a quarterback to groom behind Stafford, it would be wise if they took a long middle round look at Mannion, one of the most productive quarterbacks on the west coast. His statistics aren’t overwhelming considering he’s proven mistake prone (54 career interceptions), but he has NFL size to survey the pocket and an arm capable of making all the throws. He’s also been trusted to be a pro-level decision maker for Mike Riley. His week at the combine will help him rise or fall in the minds of many, and could make him accessible or inaccessible to a team like Detroit.
