Bell was mostly a running QB at Oklahoma before being moved to TE when Baker Mayfield took over: https://www.sports-reference.com/cfb/players/blake-bell-1.html

Hence the nickname "The Belldozer". ;)

Point taken on not wanting him to take too many snaps as a rusher if Zeke went down. Although, an occasional one would be a nice way to throw the defense off balance and give future opponents something else to think about.

I would rather see Olonilua and the winner of the Dowdle/Anderson battle stashed on the PS. Olonilua would get more time to learn the FB position, provide a FB to simulate plays for the defense and be available for call up in case of injury.

I guess it really all comes down to numbers and versatility. I'd rather see them roll with Bell as an H-Back/ST and protect DiNucci as a 3rd QB and not have to go short somewhere else than to keep Olonilua as a dedicated FB/3rd RB/ST player.
