Arriving from the college ranks in 2010, Pete Carroll has succeeded in rebuilding the Seattle Seahawks' suddenly stacked roster with a bold, unconventional approach.
If reports out of the Philadelphia Eagles' voluntary minicamp are any indication, former Oregon coach Chip Kelly's sweeping changes are going to make Carroll's methods seem orthodox by NFL standards.
It's not the just the personalized smoothies, heart monitors, customized sleep tests, positional indifference in locker-room setup and music during practices.
"His playlist is pretty cool," outside linebacker Vinny Curry said. "I'll give him that."
Kelly's up-tempo offense is going to send ripple effects throughout the NFL.
"From a communications standpoint, it's going to change the league. I'm not going to tell you guys how, but it will," tight end Brent Celek said, via Philadelphia Magazine. "It's something that I never even thought was possible in the NFL. Seeing the stuff he's doing, he has a reason why he does everything that he does, and a reason why each play is called what it is. And it all makes sense."

Influenced by Kelly, the New England Patriots already have succeeded with a one-word, no-huddle attack that had defenses struggling to maintain pace last season.
"Yeah, but it's deeper than that," Celek added. "It's pretty cool. It's all thought out to the Nth degree."
Kelly's off-field changes are designed to maintain peak performance for a significantly faster on-field pace. As offensive lineman Todd Herremans said last month, "Everything he does is linked to winning."
