Taking advantage of Keenan Allen's season-ending injury, Williams broke out in Year 2, cracking 1,000 yards with high efficiency (15.3 YPC, 5th) and (8.9 YPT, 11th). At 6-4, 205 and with 4.43 40 speed, Williams has the specs of a prototypical No. 1 WR. Despite seeing double-digit targets in only three games, he had 20 catches of 20-plus yards (T-5th) and six catches of 40-plus (T-1st). Williams also saw 16 red-zone targets, but converted only two. The bad news is not only does Allen return but the Chargers used the No. 7 overall pick on 6-4, 218-pound WR Mike Williams. While Tyrell Williams is the incumbent that's earned QB Philip Rivers' trust, it's rare for a team to draft a rookie that high and not get him involved. In short, Williams has the skills to be the Chargers' top dog again, but he'll have more competition for targets in Year 3.

Williams, a practice squad member for the majority of the 2015 season, made his NFL debut in the last week of the season and recorded two catches for 90 yards, one of which was a touchdown. One of the taller receivers currently on the depth chart, Williams has always had the ability to win the ball at its highest point, but lacked the necessary route running skills to become an effective receiver. Now in his second season, Williams has shown a refined route running technique, and has earned a bit of a repertoire with Philip Rivers throughout training camp. With Stevie Johnson (knee) sidelined for the year, Williams should see additional looks at wide receiver and could be a player to target in deep leagues.

The undrafted rookie joins a very crowded and talented group of wide receivers in San Diego. Williams will battle for playing time in training camp, but he is a long-shot to make the team.
