'What's your deal?': Timeline of Jim Harbaugh and Pete Carroll's nearly two-decade-long rivalry

"Jim Harbaugh and Pete Carroll are two of the most accomplished coaches of their era. Both are quirky culture setters who have become defined by rebuilding teams into championship contenders at the college and pro levels. In many ways, these two approach the job similarly, and unlike most of their peers. Carroll, 74, often wears a long-sleeved Dri-FIT shirt, sweats and sneakers at practice, even now as the coach of the Las Vegas Raiders in triple-digit heat."

"Harbaugh, 61, the coach of the Los Angeles Chargers, also has roughly the same uniform each day: a Chargers polo shirt and hat, gray pants and cleats or tennis shoes. He joins workouts, pulling weighted sleds with defensive linemen or entering push-up competitions with linebackers. For all of their similarities, the two coaches have an almost two-decade-long beef that intensified with a handshake and the phrase "What's your deal?""
