Yes; however, he failed to make the Lions's roster, and only had one other tryout before the beginning of the season with the Packers. With kickers coming and going throughout the middle of the season (eg. Saints), he did not get any offers to kick for another team, let alone tryout, until now.
I'm not saying he isn't NFL ready, but rather, I think he only gets this much publicity because he was an internet sensation. If YouTube sensations would translate into successful professional athletes, that one QB who could throw through windows would be starting somewhere, or those guys who could make baskets from rooftops would be 3-point assassins in the NBA.
