With addition of James Casey, Broncos have five tight ends and three potential fullbacks on roster

Denver signed James Casey to a one-year deal Saturday, adding a fifth tight end to their roster.

Casey will join Owen Daniels, Virgil Green, Dominique Jones, and Joe Don Duncan in Denver. That's five players the Broncos list as "tight ends," though at least one of them may be used as a fullback.

Casey has experience playing fullback and is likely the front-runner to land the job, but H-back prospect Duncan and 225-pound running back Juwan Thompson are also options.

Green can also play an H-back role, but it's unlikely that he'd be moved to fullback.

Denver carried three tight ends (Julius Thomas, Jacob Tamme, and Green) last season and carried Jones on their practice squad. They tried to re-sign Tamme this offseason before he signed with Atlanta.

The Broncos did not use a fullback last season, but with Gary Kubiak and the zone blocking scheme returning to Denver, they'll need one this year. Casey gives the team another option to choose from.

Denver also has ten selections to use in the upcoming NFL draft. Denver may select a "true fullback," and there's one or two draftable candidates — Alabama's Jalston Fowler among them — this year, according to ESPN's Mel Kiper.

If the Broncos use all ten draft picks (that's unlikely), their roster will increase to 86 players. That would leave room for the team to sign just four undrafted free agents before hitting the league's 90-man offseason limit.

Eventually, Denver will have to cut down to 53 players. Until then, the above mentioned players will compete for the open tight end and fullback positions. May the best men win.
