I know Donovan McNabb skipping a throw on the ground to a receiver, drives Eagles fans crazy. He shouldn't throw the ball on the ground,. but it's good that he's trying to throw the ball down, rather up. Peyton Manning threw a couple of high throws on Sunday which became interceptions.
A lot of football fans don't know this but quarterbacking is much like pitching in baseball. They tell a pitcher be wild low, rather than wild high. A pitcher who is wild low will wind up with a walk or ground out, but the pitcher who is wld high, winds giving up a lot of home runs.
When it comes to quarterbacks, a guy who is wild low, winds up like McNabb with an incomplete pass, but a guy who is wild high, winds up committing costly mistakes that usually get you beat. Manning had two interceptions and both of them were on tipped balls. The tipped balls occured on high passes which hit off of the hands of the receiver and was caught by the defenders standing behind them.
Remember this the next time McNabb throws one into the ground.
