The Minnesota Vikings have tried unsuccessfully to turn Joe Webb's elite athleticism into reliable NFL productivity, and his time is running out.

Entering the fourth and final year of his rookie contract, Webb's last chance to warrant a part in the team's future has arrived: as a wide receiver.

Webb was switched from quarterback this spring after veteran Matt Cassel was signed to be Christian Ponder's backup. The Vikings saw little purpose in keeping a sixth-round draft pick from Alabama-Birmingham with exceptional breakaway speed and leaping ability but questionable accuracy as a third-stringer. So they're hoping Webb can now find his niche at a position he's played some in the past.
