Benjamin Watson 2015 Stats: 74 receptions, 825 yards, 6 touchdowns In an atypical move, the Ravens were aggressive out of the gates in signing Watson as an unrestricted free agent, showing their desire to snag him. The 35-year-old veteran is coming off a career year in New Orleans, and his challenge will be to replicate that in Baltimore. The Ravens wouldn't have signed Watson to a reported two-year, $8 million deal if they didn't plan on giving him a lot of snaps.

Crockett Gillmore 2015 Stats: 33 receptions, 412 yards, 4 touchdowns Last year's starter was a force to be reckoned with when healthy. Gillmore showed reliable hands and was extremely difficult for opponents to bring down. Problem was Gillmore was rarely healthy. Shoulder injuries plagued him and he was placed on injured reserve after 10 games due to a back injury. After getting surgery on one shoulder this offseason, the third-year target needs to get healthy and stay that way to reclaim his starting position.

Maxx Williams 2015 Stats: 32 receptions, 268 yards, 1 touchdown Last year's second-round pick had a successful rookie campaign, breaking the Ravens' rookie tight end franchise records in catches and receiving yards. Still just 22 years old, Williams has room to grow. A player's biggest leap is generally from Year 1 to Year 2, and it will be interesting to see what strides Williams makes this summer.

Dennis Pitta 2015 Stats: N/A Pitta hasn't played since 2014 due to his second major hip injury. It's been a long rehabilitation process, but Pitta is finally back on the field. The main goal now is for Pitta to remain healthy. Any kind of setback with his hip would be a disaster. He's also got to shake off the rust and show he can get back to his prior form when he was one of Joe Flacco's favorite targets.

Nick Boyle 2015 Stats: 18 receptions, 153 yards Boyle was off to a good start last year before a suspension for performance enhancing substances ended his season early. He's a big, blocking tight end who also showed he can sneak out and catch some passes. Like Gillmore, he's very difficult to bring down. Boyle received a second suspension this offseason and will be out for the first 10 games. He has to prove this summer that he deserves a spot when he's eligible to return.

Darren Waller 2015 Stats: 2 receptions, 18 yards Waller is making the switch from wide receiver to tight end, a position that some coaches and scouts envisioned for him during the pre-draft process last year. At 6-foot-6, 245 pounds, Waller has the body to be a mismatch problem as a receiving threat. He'll have to improve his blocking and show that he can indeed stretch the middle of the field as a tight end, while likely taking bigger hits.
