Kamar Aiken
It amazes me how underappreciated this guy is.
In 2015, Aiken finished with a team-leading 944 yards and five touchdowns. However, 50 of his 75 targets came from a monstrous eight-game stretch, which accounted for 611 yards and three TDs of his total. By the way, that stretch began when quarterback Joe Flacco tore his ACL in Week 10 against the St. Louis Rams. So Aiken was making the likes of Matt Schaub and Jimmy Clausen look good.
This proved that Aiken can be durable, consistent, and a big-time red zone threat.
