It's a big ask to have 3 or so of the Olineman back from last yr to magically improve dramatically but here's to hoping. I suspect Rusty Feth will get a starting guard spot. Which one I'm not sure. Will Parker get the RT spot? The competition will be for that and the other guard spot. Be it him Stephens, Colby, Dunker and DeJong I see 5 dudes fighting over 2 spots.The last two seasons were a combination of bad factors all hitting at once. Recruiting misses, early graduation of the good OLs, no depth, and a QB who had ZERO ability to scramble and even less pocket presence.
The Ferentz boys did not forget how to coach OL the last two years. They know more than anyone that the OL sucked and needs to get fixed ASAP. Experience returning, influx of two good transfers, should get things moving in the right direction. A playmaking QB will also be a big help to the OL and the playcalling.
I think Richman and Jones are the only two I see entrenched with their spots pretty much. The other 3 could be a game of musical chairs and I wouldn't want to have to bet on who'll get what exactly.
