I first heard about him when the Jets met with him this month. He is a JUCO player who declared early for the NFL draft. There is some tape of him on YouTube but obviously it is against JUCO level players so I'm not really sure what to read into it. He is 6'3" and 220 lbs, was a track athlete and ran a 10.7 second 100-meter, a 4.39 40-yard dash, and was expected to transfer to Oklahoma before opting to declare.
Here is the previously mentioned YouTube, obviously he will be facing much better tackling and won't be able to leverage corners 40 yards downfield in blocking in the NFL, but still an intriguing prospect:
If anyone knows anything else about Gardner, I'm eager to hear it!
