Junior Steven Thompson and senior Caleb Toney are battling for the quarterback spot.
Toney, who is also working at halfback and fullback, will play on the offensive side either way.
If Toney is not the starting quarterback, he'll likely be used in short-yardage situations if nothing else.
“Caleb's a 400-plus pound squatter and he's so strong,” Rose said. “Steve's a little quicker and he's got some moves, but they both have things that set them apart.”
Other players who could fill the running back and receiver spots are Cameron Burge, Hunter Gomez, Mitchell Gomez and Bryan Williams.
Most figure to see time in the defensive backfield as well.
“We want to try to keep those guys as fresh as we can, but we're going to have to use some of them on both sides,” Rose said.
Also on defense, the Titans bring back a strong front end, including linebacker Chevin Noone, who could also see time as a short-yardage fullback.
“We're pretty green but there's some positive things there,” Rose said. “It just might take some growing pains early in the season to get there.”
