Sherman and Gronkowski star in digital short series

Richard Sherman, now one of football's most prolific pitchmen, said he doesn't have some master plan to craft a particular image in his endorsement choices.

The Seattle Seahawks cornerback has starred in ads showing how he deals with claims that he's the best in the game.

The digital short series for Oberto that launches Thursday features Sherman and the New England Patriots tight end sitting in a garage and riffing on a variety of subjects.

Gronkowski started an Instagram account last month, announcing it with a video that opens with him on a slide at a playground.
