THE CHALLENGE: Create one last hurrah for Reebok before relinquishing NFL official licensing to Nike, using 20 of their top sponsored players (Eli Manning, Peyton Manning, Kevin Boss, Jerricho Cotchery, Greg Ellis, Matt Hasselbeck, Madison Hedgecock, Chad Johnson, Thomas Jones, Mathias Kiwanuka, Nick Mangold, Laurence Maroney, Jeff Saturday, Bo Scaife, Derrick Ward, DeMarcus Ware, Ty Warren, Benjamin Watson, Reggie Wayne, and Vince Young). The result was “Migration,” where the guys are compelled by something in the air to return to their home fields as autumn approaches. For them, football’s more than a job. It’s instinct.
