‘John Fina, the son of a physician, earned numerous academic awards when he played football at Arizona. He majored in psychology and could talk for hours about the human mind. But sometimes, it all comes down to mathematics. "You know, when they have eight or nine guys on the line of scrimmage, you can only block six or seven of them," Fina said late Sunday afternoon. "That’s how the math works." Simple arithmetic also says the Bills beat the Packers, 27-18. It says they’re the only 2-0 team in the AFC East. Rob Johnson put some impressive numerals on the stat sheet, completing 18 of 26 passes for 259 yards and three touchdowns. Still, Fina has a point. Despite putting 27 points on the board, the Bills had a serious math problem. For the second week in a row, they were outnumbered by the opposition blitzes. Football is essentially a game of blocking and tackling. Buffalo is doing just fine in the tackling department. It’s the blocking that leaves a lot to be desired.’
