I agree that you can't definitely say Stanley will make it through another season with that ankle-lower leg issue, but somehow he played through it last year and while he wasn't the Stanley of old, he was satisfactory. He might suffice again though of course I'd prefer a longer term more sound solution.
But it's hard to replace your starting LT, LG, C, RG, & RT while bolstering your defensive line along with it. We'll have to depend on coaching for making improvements this year. I think good coaching can get the O-line to be respectable but with the talent that's there I don't expect it to be dominant.
