There questions, no doubt. But that doesn't mean there aren't good answers. Collins should be good by opening day. While it's true Smith is always fighting an injury, it's also true that he doesn't miss a lot of time, and his taking time off at TC is likely only a precaution. Williams is said to be recovering well and is getting his share of reps. Then we have Biadasz and McGregor who are unknowns to a degree because they haven't seen any playing time yet, but they are both well regarded and may help solidify things. So yes, questions, but a lot of potential answers. I don't think the O-Line will be at it's dominant peak of a few years ago, but I'm personally optimistic that it will still be a good O-Line.
