The Baltimore Ravens didn't get much immediate return on this seven-member draft class outside of first-round pick Marlon Humphrey. It has prompted many to wonder why the Ravens chose Tyus Bowser over JuJu Smith-Schuster in the second round and selected Chris Wormley and Tim Williams over Kareem Hunt in the third. Baltimore's offense would've certainly looked much different and explosive.

Grade: Below average

Best rookie: Marlon Humphrey, CB, first round. There's no debate here. Humphrey was the only Baltimore rookie to play over 200 snaps this season. While many wanted Baltimore to take tight end O.J. Howard with the No. 16 overall pick, Humphrey is looking like he's going to be a top-tier corner. He stepped into the starting lineup after Jimmy Smith suffered a season-ending Achilles injury and there wasn't much of a drop-off. The Ravens were impressed with his composure and tight coverage when lined up against the likes of Antonio Brown, T.Y. Hilton and A.J. Green. He finished with two interceptions and 11 passes broken up.

Most improved rookie: Chuck Clark, S, sixth round. He developed into a core special-teams player and earned more snaps on defense with his physical play, moving ahead of Lardarius Webb on the depth chart by the end of the season. Clark finished with 13 tackles, which were the second-most by a Baltimore rookie this season. His football IQ has made him a favorite of the coaching staff. Clark has the potential to grow into an Anthony Levine-type role for the Ravens.

Most disappointing rookie: Take your pick -- Bowser, Wormley or Williams. These three players were among the first 78 players drafted this year, and they combined for 22 tackles and three sacks. Bowser showed some flashes, but he played over 15 snaps in just two games. The Ravens haven't fared well with their second-round picks in recent years, missing on linebacker Arthur Brown (2013), tight end Maxx Williams (2015) and linebacker Kamalei Correa (2016). As far as the team's other highly drafted defensive rookies this year, Wormley and Williams were healthy scratches for a total of 13 games.

Jury is still out on ...: Nico Siragusa, OL, fourth round. He suffered a torn ACL, PCL and MCL in his left knee on the sixth day of training camp. Baltimore really could have used the first offensive player drafted by the team in 2017. The Ravens lost both starting guards in Marshal Yanda (ankle) and Alex Lewis (shoulder) to season-ending injuries. Baltimore was also without its top interior backup in John Urschel, who abruptly retired before the first practice of training camp. Siragusa can serve as the team's No. 3 guard or look to play center if Ryan Jensen isn't re-signed.

Undrafted rookie evaluation: Patrick Ricard primarily became a fullback after being signed as a defensive lineman. Ricard had some growing pains early, but he made an impact later in the season. His two touchdown catches as a rookie are one shy of what 2015 first-round pick Breshad Perriman has scored in his three-year career. Two other key undrafted rookies, cornerback Jaylen Hill and linebacker Bam Bradley, dealt with injuries. Hill suffered a torn ACL and MCL in Week 16, which could affect his status for 2018. Bradley, who suffered a torn ACL in Week 2, should be a core special-teams player next season and could compete for the starting job at inside linebacker next to C.J. Mosley.
