One quarterback left the field with his helmet on, wearing it more for refuge than protection, moving like his cleats were made of lead.
The other quarterback left much later, after hugging everyone in sight and conducting television interviews, his helmet off, grin radiating, fans screaming his name.
The first quarterback threw for 381 yards and three touchdowns, setting a franchise rookie record for passing yards in a game.
The second quarterback won.
Sunday, Tebowing beat Pondering, and by the end of the day Tim Tebow's successes and Christian Ponder's failures no longer seemed so mysterious.
Tebow, the Broncos' lightning rod, is 6-1 as an NFL starter. Ponder, the Vikings' rookie, is 1-5. Both quarterbacked proud college teams in Florida. Both run like halfbacks. Both were first-round draft choices taken earlier than most analysts expected, and both were asked this season to resurrect losing teams.
Ponder is the more accurate and prolific passer. Sunday, with star running back Adrian Peterson and veteran receiver Michael Jenkins injured, he shredded Denver's defense.
Tebow's throwing motion is long and awkward. He's as likely to run the option as he is to complete a touch pass, and he'd probably lose a 40-yard dash to Ponder. Somehow, though, through a combination of luck, timing, clutch play and his counterpart's mistakes, Tebow made the difference in the Broncos' 35-32 victory at Mall of America Field.
