I understand his point: power conference teams have so many more chances to pick up "quality wins."
The problem is reliance on arbitrary RPI Top X records in aggregate. Winning % in those games is often treated as less important than raw numbers, because it's figured that if you played in more of those games then your strength of schedule is more impressive. I've said this elsewhere already, but who is better, a team that's 2-1 against the Top 50 or one that's 5-7? The truth is that we don't know just based on that, for a number of reasons including the fact that home/road isn't factored in and the sample size in general, but if the 5-7 is in a major conference and one or two of those wins is on the road against a top seed their "resume" is often seen as more impressive.
I disagree with Bilas' solution, for obvious reasons. But bracketologists and the committee need to get away from these team sheets and nitty gritty's organized by RPI range wins. KenPom's A/B tiers is slightly better, since at least that factors in home/road and isn't rooted in RPI. A de-emphasis on the sheer quantity of wins would accomplish the same result that Bilas is looking for.
To further my point:
