I was very surprised we didn't sign Joe Newton, Jonny Harline, Daniel Coats, Matt Trannon, Dan Murray, Matt Herian, Julius McClellan, Anthony Pudewell, Rodney Hannah, Cody Boyd, Zach Herold, Chad Upshaw, or Rudy Sylvan.
Braden Jones has off-the-field issues, and Mueller and Cameron seem to be steering clear of guys with any "character" concerns.
I don't think Samuel Smith from FIU has signed with anybody. But there again, maybe there's a "character" issue because he was suspended for that brawl with the Canes.
I'd never heard of Jake Nordin, Jon Hamlett, Kendrick Ballantyne, Luke Smith, Matt Farbotko, Michael Mathews, Marcus Freeman, or Steve Buches before I read your post.
The only thing I can figure: We weren't able to sign any of the guys we liked. And didn't consider any of the other guys an upgrade over the TEs we already have on our roster.
