It's easy to blame the play-calling when the offense is not scoring touchdowns. Marv Levy used to say it is not important what play is called, it is the way the players perform the play on the field that makes the difference. I can think of three plays that would have led to Bills touchdowns if they had been executed properly:
The Bills are on the Kansas City 5-yard line and Bledsoe goes back to pass. Phillip Crosby goes out of the backfield into the right flat. He is not picked up by the defense. All Drew has to do is complete a swing pass for an easy touchdown. Instead, he throws the ball over Crosby's head.
Drew completes a pass in the right corner of the end zone to Eric Moulds that is first ruled a touchdown, and then overturned when the review shows Moulds has one foot out of bounds. The replay shows that Eric catches the ball with one foot in bounds and has plenty of space to drag his foot on the ground to complete a legal catch. It is a standard play that most good receivers execute automatically when they are near the sidelines. Moulds fails to do it, costing the Bills a touchdown.
The now famous deep pass to Peerless Price with four minutes to go. I don't know about you but I'll take a touchdown anytime the Bills are behind. It was a good call, Price was open, Drew had time, but his throw was short and behind Price allowing the defensive back to make an interception.
Kevin Gilbride put his two best players in a position to win a football game. You can't blame him for that. The fact that things did not work out had nothing to do with the play calling.
