2. Tight End
Jermaine Gresham is the only established name in a barren tight end group, and he enters the season at 30 years of age and coming off an Achilles injury.
Ricky Seals-Jones has endured an offseason blighted by off-field incidents. However, the 6-foot-5 and 243-pound converted wide receiver is the most likely candidate to step up and contribute.
A quarter of his 12 catches in his rookie year went for touchdowns.
With rookie quarterback Josh Rosen looking to take over starting duties from the veteran, Sam Bradford, at some point this season, an offensive playmaker like Seals-Jones will need to be a major contributing factor.
