Rookie glance: TE Nick Kasa

How acquired: Sixth-round draft pick (No. 172 overall) out of Colorado

2013 season: The first of three sixth-round draft picks for the Raiders, and one of two tight ends drafted, the 6-foot-6, 265-pound Kasa played in all 16 games, starting at the New York Giants on Nov. 10. He began his college career as a defensive end so he has no issue mixing it up as a blocking tight end. He caught one pass as a rookie, but he made it count -- a 9-yard touchdown reception in the season finale from Terrelle Pryor against the Denver Broncos.

Looking ahead: With Jeron Mastrud about to hit free agency and Mychal Rivera having established himself as a fine pass-catching tight end, Kasa may still face an uphill battle with recuperating David Ausberry, who missed the season with a shoulder injury, returning. Still, Kasa did make contributions on special teams, and the Raiders did carry three tight ends on the roster last season. He needs to show more pass-catching skills, though.

The Raiders’ other 2013 rookies that finished the season on the roster: LB Sio Moore, OT Menelik Watson, CB D.J. Hayden, DE Ryan Robinson, CB Chance Casey, S Shelton Johnson, WR Greg Jenkins, OG Lamar Mady, QB Matt McGloin, WR Brice Butler, DT Stacy McGee, TE Mychal Rivera, RB Latavius Murray.
