What the coaching staff thinks
As previously mentioned, John Franklin is an excellent addition to the Buccaneers due to his impressive versatility. Tampa Bay can line him up across the field to general success, and having one player who can excel in multiple positions dramatically helps with the issues of roster space.
While some wide receivers can also line up at running back or on special teams, Franklin brings an even greater depth with the ability to line up at quarterback.
Bruce Arians spoke on the matter recently, and it appears to imply that Franklin could be the best of both worlds.
John Franklin wasn’t the most accurate quarterback during his college days, but having a third quarterback that can also get reps at other positions is a far better use of the roster spot than a single-position player. Currently, Tampa Bay has Ryan Griffin as the third quarterback, and he seldom touches the field.
The Buccaneers would be far better off using Franklin in the role proposed above as he could be the sixth receiver and the third quarterback. He can provide sufficient depth where needed, and he backs up multiple players meaning the Bucs would get more bang for their buck.
It also stands to reason that due to this quote, Tampa Bay may be showing that their plans for Griffin are ending, but Franklin could be a more exciting option in that role either way.
