Top Week 4 NFL picks

After simulating every game 10,000 times, the model is high on the Titans to cover as six-point favorites on the road against the Jets. Robert Saleh knew he'd have a rebuild on his hands, but his first three weeks in New York have painted a desolate picture of the current state of the franchise.

Rookie quarterback Zach Wilson has been sacked 15 times and has looked flustered by constant pressure, throwing seven interceptions and completing just 25.9 percent of his passes when pressured. The Titans rank eighth in the NFL in pass rush win rate (51 percent), so it could be another long afternoon for Wilson.

The model is predicting that the Titans record nearly three sacks and force two turnovers. Tennessee running back Derrick Henry records his third consecutive 100-yard rushing game to help the Titans win in well nearly 70 percent of simulations with a projected final score of 28-16. The Titans cover well over 50 percent of the time.
