I think this article is being a little too optimistic.
The assumption is that because Tyron had surgery on his neck the problems he has had are fixed. We do not know that. We has had problems with his elbow, back and knee I believe. None of those are fixed by his neck surgery. His neck may not be fixed by his neck surgery.
We are also assuming La'El Collins will be 100% have hip surgery. I don't know exactly what they did to repair his hip, but that's a tricky one. Collins may not come back even close to 100%.
And notice how Martin turned 30 and now is getting dinged here and there? The guy sis all-world in my book, but we have to watch for those injuries that nag older players.
Now let's get to the other two positions. Biadasz looks promising and with an off-season maybe he gets better, but he looked like he needs to get a little stronger. I do think he will be good enough and he looks like he understands how to run block. He needs to work on pass blocking which I think may come with experience and additional strength.
That leaves us with Connor Williams. Williams has a major flaw and that is he can be bullied by big strong DTs, particularly when pass blocking. But he has good feet and he is an excellent blocker when on the move., maybe the best on the team. I'd rather see someone else at LG, and maybe that's Connor McGovern. McGovern doesn't look dominating but he seems to avoid bad plays. He is clearly lacking experience, but the question is, could he take over for Williams and would that be an improvement?
I think we have to assume at least one of the OL will get hurt again next year. The Cowboys should be prepared for that.
