Hamler was both fast and quick in college. Biggest problem he had at psu was drops, which I think knocked him out of the 1st round.
Year 1 at Denver he averaged 19 yds per catch on limited targets.
the cardiac issue he had seemed to be a viral myocarditis, which typically resolves completely.
Biggest issue I see is hamstrings and acl. If he’s recovered from these, he could be the deep threat Bills currently lack.
in any event,, a pretty low risk signing. Cost the Bills no draft capital and little salary cap.
