Notable undrafted additions

Undrafted rookie free agency is a crapshoot.

But odds are good that at least a couple of players out of each AFC South class will have staying power.

Pat Kirwin of NFL.com thinks Jaguars center Mike Brewster and Titans center William Vlachos will be two of those guys.

Rob Rang of The Sports Xchange and CBSSports.com likes a bunch of defensive linemen: nose guard Chigbo Anunoby of the Colts, nose guard of Hebron Fangupo of the Texans, defensive tackle DaJohn Harris of the Titans as well as outside linebacker Delano Johnson of the Titans.

Meanwhile Todd McShay of ESPN lists 10 undrafted signees he likes in this Insider file, but doesn’t include anyone who landed in the AFC South.

I've not scouted any of these guys, I confess. But when I see teams on the field we'll check back in on who looks good and who's creating any buzz.
