For what it's worth, Adam Jahns on his podcast yesterday indicated the the current offensive line appears to be Elijah Wilkinson vs Teven Jenkins at LT, Whitehair at LG, Mustipher at C, Daniels at RG, and then Ifedi vs Borom at RT. The expectation is Jenkins wins the LT competition and its a wait and see for how long Ifedi can hold off Borom. He did say again that the Bears had a 3rd round grade on Borom.
It will be interesting to see if the Bears keep 8 or 9 offensive lineman. If you figure those 7 I named above are nearly locks to make it, then that would only leave 1-2 interior back-up positions available. You figure Bars is in the discussion. Could someone like Eiselen work himself into the discussion to make the 53 man roster?
