Video: Top 100 Week 7 Flex Rankings + Tiers
Jamar Chase at 11. The only reason why Jamar Chase is at 11 is as of right now, I don't think that we are going to see Lamar Jackson play in this game, which should trend this game towards being lower scoring.

Ranked 11th; ranking depends on Lamar Jackson's availability

Ranked 11th in week 7 flex rankings. The source notes the ranking reflects uncertainty about Lamar Jackson's availability, which would lower the game's scoring environment; if Lamar plays, Chase would move up slightly: 'The only reason why Jamar Chase is at 11 is as of right now, I don't think that we are going to see Lamar Jackson play in this game, which should trend this game towards being lower scoring.'
