Based on the signings that were reported, the Jets didn't add any wide receivers via the undrafted free agency route, but they've picked up one off the waiver wire today:
We've claimed WR Matt Cole.— New York Jets (@nyjets) May 5, 2021
The 24-year old is 5'10" and 197 pounds and was an undrafted rookie last season out of McKendree University. He made his NFL debut with the 49ers last year, seeing some time as a punt gunner and registering two tackles in his only appearance. He also spent time with Miami.
The Jets might be looking at Cole as a potential kick return option. He had some excellent kickoff return numbers in college.
Cole ran a 4.48 at Northwestern's pro day last year with excellent explosiveness numbers but poor strength and agility numbers.
