I haven't gone back and looked, but I suspect that just about every Superbowl winning team had pro bowl caliber talent on its offensive line. Ditto for teams that contend regularly. Andy Reid has always put a priority on the O-line and his lifetime record is pretty impressive. It's not that you cannot build a strong offensive line with mid-round picks and FAs, but it's certainly tougher to do and I expect that teams that DO have consistent, strong O-lines invested premium draft picks in it.
I'm not particularly interested in doing the research, TBH, but I expect analyses of these types can be found all over the web.
Edit: PS: I wasn't banging the table for an offensive lineman this year -- I love the guys they took. Just making a general observation that I think Snead puts less of a priority on the O-line than some other organizations appear to.
