here's a thought... If Lewis can actually play RT, then paying a guard in FA 5-6m/yr might not be a bad idea.?? Would mean we have a similar OL to the 2012 and 2014 teams.
2012 - Mckinney, Osemele, birk, Yanda, Oher
2014- monroe, osemele, zuttah, yanda, Wagner
2017- Stanley, FA guard, zuttah, yanda, Lewis.
I see all 3 as very similar. FA guard should be as good or better than 2012 Osemele, but lesser than 2014 Osemele. RT, C, LG, LT would all be identical.
