Video: Top 100 Week 7 Flex Rankings + Tiers
Marvin Harrison Jr. I have at 88. That's right in line with where he would be at in the prop markets which I think is is sort of interesting. actually makes me the highest on him on the site. The reason why I'm comfortable ranking him this high is I think they're going to be winning by a billion against the Giants and they'll be able to try and force him a touchdown.
