It took Matt Cassel just two games to deftly summarize his career.
In Game 1, DiploMatt, the nice-guy professional who makes everyone comfortable, eased the Vikings to a 34-6 victory over St. Louis while playing flawlessly.
In Game 2, facing a superior defensive coach and lacking a star running back, HazMatt, the toxic quarterback, threw four interceptions, dooming the Vikings in their 30-7 loss to the Patriots at TCF Bank Stadium.
DiploMatt can make the best of a good situation. DiploMatt won 11 games with an excellent Patriots team in 2008, and won 10 with a previously inept Kansas City team in 2010.
HazMatt has gone 13-27 in his other five seasons, dooming his stay with the Chiefs in 2012 by throwing 12 interceptions and fumbling eight times in nine games.
DiploMatt runs the offense with discipline.
HazMatt stares down receivers so long defensive backs have time to Xerox blocking schemes for their interception returns.
If the Vikings are using kid gloves with rookie Teddy Bridgewater, they need to wear yellow jumpsuits when they approach Cassel.
