Williams finally got out of target hog Keenan Allen's shadow only to land in an even bigger one, Antonio Brown's. The news isn't all bad, though. The Raiders have far less depth on offense than the Chargers, and Williams is easily the No. 2 option in the team's passing game, with only diminutive speedster J.J. Nelson and pedestrian journeyman Ryan Grant offering any depth and no tight ends of which to speak. At 6-4, 205, Williams is tall, lanky and unusually fast (4.42 40) for a receiver his height. He's averaged more than 10 yards per target the last two seasons and hauled in four catches of 40-plus yards on only 65 targets a year ago, i.e., he's been a big-play weapon throughout his career. Williams was rarely used by the Chargers in the red zone, but he's easily the tallest viable option the Raiders have and should see more looks from in close this year. Derek Carr is hardly Dan Marino, but he'll have plenty of attempts in a Jon Gruden offense, so there will be enough targets to go around even after Brown has taken the lion's share.

Williams broke out in 2016 with 1,059 yards, seven TDs and six catches of 40-plus yards, but the Chargers, despite getting a healthy Keenan Allen back, drafted Mike Williams with the seventh overall pick last year. Allen had a big year, but a back injury derailed the younger Williams, and Tyrell Williams got chances, albeit fewer of them, and arguably performed even better. He upped his per-play numbers to 16.9 YPC and 10.6 YPT, and managed three 40-yard catches on only 69 looks. At 6-4, 205, and with 4.43 speed, Williams is just as tall and much faster than last year's first-round pick, but it's likely the Chargers will do whatever they can to get a return on such a large draft-day investment. That would make Tyrell Williams the team's No. 3, and that's not counting Travis Benjamin (67 targets), who could be cut.

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.
