FLORHAM PARK, N.J. -- It's one of the most unstable coaching jobs in the NFL. Average shelf life: About 1½ years. It screams, "Rent, don't buy!"
The position: New York Jets, offensive coordinator.
The next man up is Tanner Engstrand, 42, a first-time NFL coordinator who worked under big-name coaches Jim Harbaugh and Ben Johnson while taking an unconventional route to the Jets.
Engstrand last week proclaimed himself "100%, absolutely ready" for his new gig, which has swallowed up his predecessors.
He's their 10th offensive coordinator and the 11th playcaller in the past 15 seasons, a staggering run of volatility.
