Undrafted free agents don't always get the respect that they deserve, especially for a team like the Jacksonville Jaguars. UDFAs are typically below the grade, but each deserves a fair shot, and it may surprise you who makes the team and who doesn't.
UDFAs can turn out to be vital role players or even more. It really becomes a case of preference with the staff, or the player can just flat-out perform in practice. It's the former that makes the UDFA process so interesting.
For whatever reason, and there are a variety of reasons, some impressive talent gets bypassed in the draft.
