As Paul Kuharsky mentioned this morning, signing undrafted free agents will be a challenge for the Titans because they are already so deep. About the best thing an undrafted guy can hope for if he comes here is a shot at the practice squad. There aren't to many guys that are willing to settle for that.
Here are the guys the Titans have signed so far:
WR, Dudley Guice (NW State)
DE, Mitch King (Iowa)
OL, Ryan Schmidt (South Florida)
QB, Alex Mortensen, Arkansas/Samford (Yes, he is Mort's son)
RB, Rodney Ferguson (New Mexico)
CB, Jeremy Haynes (McNeese State)
WR, Phillip Morris (South Carolina State)
P, A.J. Trapasso (Ohio State)
I will update the list when/if more guys are signed gramsey finds them!
