Happy Birthday, Bruce Arians! You're the only coach who can step in as an interim and casually snag NFL Coach of the Year honors. Seriously, most people can't even find their keys when filling in temporarily—meanwhile you were busy turning around the Colts' season back in 2012.Then again, your first full-time gig with Arizona wasn't too shabby either. You took those Cardinals soaring higher than anyone expected—and did it all while rocking hats cooler than any playbook could diagram. Here's to another year of bold calls and stylish sidelines; may your birthday be filled with touchdowns and zero penalties!
