The Facts: If even a sliver of doubt festered in the recesses of the minds of Titans fans about whether Mariota would start Day 1, HC Ken Whisenhunt erased it Thursday when he was asked about his QB pecking order. "You mean after Marcus?" Whisenhunt asked.

Diehards Line: It's clear that Mariota is the starter as training camp kicked off Thursday and will be when the Titans face the Tampa Bay Buccaneers to open the season. The No. 2 overall pick in the draft has progressed well during offseason workouts, according to Whisenhunt, but the team doesn't want to overload the rookie -- including too much off-the-field marketing as the face of the franchise.
