Alexander is one of the better young linebackers in the league, but IDP owners have only gotten one full year out of him. As a rookie in 2015, Alexander served a four-game suspension for violating the NFLís policy on performance-enhancing drugs, but he had 93 tackles, three sacks and two interceptions in 12 games. In 2016, he tied for fourth in the league with 145 tackles. But last year, a hamstring injury cost Alexander four games, and he finished with 97 tackles and three sacks. If heís able to play a full season in 2018, Alexander should be a top IDP performer.
