TAMPA — He has yet to take a single snap this season, but Bucs QB Mike Glennon said he has worked to stay focused and continue developing as a passer while serving as a backup to rookie Jameis Winston.
"All you have to do is look around the league and see how many guys have played — I bet over half the teams have had (backup) guys go in and play, and not just for a few plays, but start and play significant time," Glennon said Wednesday. "I'm just helping Jameis as much as I can, doing whatever I can to help this team win, that's the mentality I've had. It's fun to be a part of more of a winning team and be in it toward the end."
Winston is one of just four in the NFL to attempt every QB pass for his team this season; New England's Tom Brady, Jacksonville's Blake Bortles and Washington's Kirk Cousins are the others. But seven teams have had to use three or more quarterbacks, and the Texans have used five.
Glennon, 26, was fortunate enough to play extensively in his first two seasons, taking over for Josh Freeman in 2013 and for an injured Josh McCown last season. He had a combined 18 starts, throwing for 4,025 yards with 29 touchdowns against 15 interceptions.
"You learn something from (offensive coordinator) Dirk (Koetter), you take things away from the good things Jameis does, the things he can learn from, too," Glennon said. "You always try to make it a learning experience, whether you're playing or not."
The team has carried a third quarterback all season in Ryan Griffin, claimed from the Saints before the season started, and if the Bucs feel comfortable with him as a backup to Winston, they could be in better position to trade Glennon for a draft pick to a team that thinks he can compete for a starting position in 2016.
"My focus right now has been on the season," Glennon said. "Once the offseason comes, which is not too far away, I'll start putting more thought into that."
TRANSACTIONS: The team continues to get a jump on offseason signings, placing WR Vincent Jackson on injured reserve with a knee injury and using his roster spot to promote S Kimario McFadden from the practice squad.
McFadden is the fourth player promoted from the practice squad since the start of last week, joining RB Mike James, WR Evan Spencer and TE Tevin Westbrook. Jackson was limited by injuries to 10 games this season, finishing with 33 catches for 543 yards and three touchdowns.
The team also signed three players to fill out its practice squad, adding former Louisville S Gerod Holliman, former Appalachian State CB Joel Ross and CB C.J. Roberts, who played at Colorado State-Pueblo. All three are rookies who haven't played in any NFL games. Holliman, who led the NCAA with 14 interceptions last season, was drafted by the Steelers and cut in preseason.
INJURIES: Only two players missed Wednesday's practice, CB Sterling Moore (ankle) and LG Logan Mankins (knee), and coach Lovie Smith said he expects both to be able to play this week. S Chris Conte, who missed Sunday's game with a knee injury, was back practicing in a limited capacity.
