Over the next couple of days we will take a look at each of undrafted free agents to get to know them a bit, but also so they get their chance to show what they’ve done to get here.

Today we take a look at Ole Miss wide receiver Harrison “Trey” Wallace III. From the team: Harrison Wallace III (6-0, 192) started all 15 games last season at Mississippi and had 61 receptions for 934 yards and four touchdowns, helping the Rebels to the College Football Playoff and an appearance in the Fiesta Bowl at State Farm Stadium. He began his college career at Penn State and played 39 games (21 starts) during his four seasons with the Nittany Lions.

Wallace had 84 receptions for 1,221 yards and six touchdowns during his time at Penn State. Wallace has been ultra productive the last two seasons, finishing with 107 receptions for 1,654 yards and eight touchdowns, while playing into the College Football Semifinals in back-to-back seasons. The issue is he is a very one-trick player right now.

From Lance Zierlein: Wallace is a leggy long-strider who played deep into the College Football Playoff in consecutive seasons at Penn State and Ole Miss. While his catch production has jumped in the last two seasons, he has trouble beating press and uncovering over the first two levels, which makes it tougher to project continued improvement as a pro. While he’s likely to see a higher number of contested catches, he’s built for it.
