Most of the top teams invest in the OL with top picks. Look at all the playoff teams and tell me what percent of them haven't invested high picks in their OL.
So yeah, you can always find a team that doesn't do it with high picks, but as Damon Runyon once said:
"The race may not always be to the swift nor the victory to the strong, but that's how you bet."
the main point here is that while it is possible to win without investing top picks on the OL, it's not the safest way. When guys have top tier talent it can cover for errors due to lack of cohesiveness or mental mistakes. And I would argue there isn't one guy on the OL who is a top tier talent with Whit being so old now. I am willing to bet that there isn't an OL who will sniff the pro bowl on this OL.
