The Lions signed undrafted free agent WR Jonathan Adams out of Arkansas State. Adams puts a big check mark in the measurables box, going 6’2 and 210 pounds with a huge 39-inch vertical. He puts that to good use, flashing plus ball skills and contested-catch ability on tape. He’s coming off a big 1,111-yard, 12-TD senior season, accounting for 28% of his team’s receiving yards and 31% of the TDs. Adams obviously faced weaker competition in the Sun Belt conference but did post a 8-98-3 line on Kansas State this past year. We wouldn't be surprised if he made Detroit's roster -- although he obviously has a long ways to go to be a fantasy factor.
