If you pay any attention to pro football, you'd know for the first time in NFL history two brothers will coach against each other in the Super Bowl. Harbaugh vs. Harbaugh will become a played-out storyline in the coming weeks, but Mike Florio believes it's acceptable because this is a significant moment in football history. Only 15 months apart in age, John and Jim Harbaugh's story is remarkable - both are coaches at the highest level, both led their team to the biggest stage, and both have the determination to beat the other. This will be the first time these two coach face each other in a Super Bowl, but it may not be the last.
