The sponsor that left was the Buffalo Bills. Kozak assumed the team was in for its usual portion this season, which amounted to a sixth of the budget, but they weren't.
So long story short, they couldn't come up with 1/6 of the funding, I am the last one to defend Ralph's cheapness, but are you kidding me? They place 100% of the blame on the Bills their own financial insecurity. That just seems to be the mindset in America right now, if you're not happy with your situation, blame someone else.
