2014 base salaries for guards:

I know these don't tell the whole story about the kind of contracts the players are signing, but they're an indicator of the average.
Direckshun threw out a 3 years 8 million figure. Plus the signing bonus, that'd average out to 3-3.5 million a year for Schwartz. That puts him in the range of Louis Vasquez, Dan Connolly, Todd Herremans, Chris Chester, TJ Lang, and Donald Thomas (22-17)
I don't know about everyone else, but with the market as it is and the way Schwartz played once he took over for Asamoah full-time, I'd be willing to do that and more.
In this case, I'm all in favor of throwing money at the problem instead of draft picks. Keep Rishaw Johnson and Rok Watkins hungry for Jeff Allen's job. Mix competition with chemistry. It's about time we fixed the offensive line once and for all.
