Interesting thought if you're Vrabel... What game/outcome do you think is more important to the Titan's season/success:
The Texans are a divisional game, but they are 1-4 and may not pose a threat to the division title. Maybe they turn it around and can fight for a wild card spot.
The Bills are 4-0 but they still play in a division with the Pats. If they don't win their division, they too will be fighting for wild card seeding. If the Titans and Bills both win their divisions, then we are fighting for seeding and maybe MAYBE a playoff bye.
That said, do you try to push players from COVID/injury back, potentially risking more injuries with no real practice, and give it your all against the Bills? Or do you take caution and leave players on the COVID list, sit out AJ, AJ, and Lewan? Give them extra time to heal up, get prepped, and a full week of practice before the Texans.
