The rich got richer in a Week 8 when the top teams like Philadelphia and New England continued to roll, and there were no meaningful upsets. Here is what we learned in N.F.L. Week 8:

■ Houston Texans quarterback Deshaun Watson is remarkably fun to watch, even in a loss. Watson is a rookie, and will make some rookie mistakes — like the interception he served on a platter to Earl Thomas, who returned it for a touchdown, or the two times Watson failed to account for Richard Sherman in coverage and paid for it with interceptions — but Watson went out and nearly beat the Seahawks in Seattle on Sunday, outdueling Russell Wilson for much of the game. Wilson ended up winning with a stunning touchdown pass in the final minute, but Watson showed absolutely no fear of Seattle’s secondary and threw for 402 yards and four touchdowns, two in the fourth quarter. And he did most of it with a smile.

■ It is no fun to play in Buffalo. The Bills won again, making them 4-0 at home and 5-2 over all. The defense forced four turnovers despite injuries to two starters and the team’s having traded away Marcell Dareus, and the offense continued to hum along in its quiet way, with Tyrod Taylor passing for one touchdown and running for another, while LeSean McCoy rushed for 151 yards. Next week the Bills will take their act on the road, where they have been far less fearsome.
