For the 21-year-old rookie, he gets a chance to take a breath during what's been an up-and-(mostly) down season, and watch a veteran journeyman show him what it means to be a "true professional," as head coach Todd Bowles called Josh McCown earlier this week.
McCown had a career year last season, with 18 touchdown passes and 13 turnovers in 13 games before he got his hand broken on a sack Week 14 in Denver. He was even more impressive at home, going 4-3 with wins over three playoff teams in the Jags, Bills and Chiefs. The three losses were all by eight points or less, also to three playoff teams (Patriots, Falcons and Panthers).
We still don't know who the Bills' quarterback will be Sunday, but does it matter? Rookie Josh Allen, another journeyman in Derek Anderson and the already infamous Nathan Peterman have combined for three touchdown passes and 16 interceptions this season, and the Bills have scored 20 points combined in their last three games.
The Jets are on a three-game losing streak and Bills on a four-game skid, while both teams are 3-6 against the spread. I expect New York to get to 4-6, both SU and ATS heading into its bye week.
After that, who knows? The Jets say they'll return to Darnold once he gets healthy, but with two games against the Patriots, visits from Aaron Rodgers (Packers) and Deshaun Watson (first-place Texans) still to come, how many more wins can they realistically get?
Prediction: 21-10 Jets
