Under any scenario:
There will not be consistency on the offensive line.
Last year the starting line was Solder-Mankins-Wendell-Connolly-Vollmer.
There will be a new LG that Solder will have to work with.
There will likely be a different center, and that spot could change again if Stork takes it over mid-season.
If Connolly is at Center, then there is a new RG for Vollmer to work with.
And, of course, there is a new coach.
Further, there aren't many pure guards on the roster.
Connolly is a Guard/Center and has performed better at Center.
Cannon has been playing RT and LT all preseason, and was a college Tackle.
Devey, at 6-6, is a tall Tackle playing Guard.
Fleming, if in the equation, is a Tackle without experience at Guard.
Halapio is a stretch to make the roster.
Kline is really the only pure Guard.
