SB Nation's Mile High Report has turned in a long list of unconfirmed signings for the Broncos undrafted free agents
MHR explains what the Broncos are trying to do with these UDFAs:
What Denver will be looking for here are primarily players who may not have measured up to the highest standards of their position, but who can upgrade overall depth quality, amd most importantly, who can develop a role on special teams coverage units.
Here's the unconfirmed list from MHR:
LS Clint Gresham
TE Nathan Overbay
DT Jaron Baston
TE Michael Palmer
CB Cassius Vaughn
DE Brandon Gilbeaux
SS Marty Bowman
OT Chris Marinelli
WR Alric Arnett
OL Michael Shumard
RB Chris Brown
OLB Kevin Alexander
MHR has a pretty cool breakdown of each player. They've also grouped them by position and determined how many players at each position group will be carried to camp.
