I'll be surprised if we don't bring in another kicker right before camp. I have no issue with Liegghio, his college career is certainly impressive, but at least for a little insurance it would be nice to have another camp leg.
As for the backup quarterback position. I tend to agree with TBurg on this one. I don't even like Jennings but there's something to be said for having some experience of any kind. In the early 2010s we left ourselves with Brink, Elliott, and Goltz after Buck Pierce got injured and two of those guys couldn't even throw a football.
