This pick probably wouldn't be ranked No. 1 if it had actually ended up being Philip Rivers. Then again, maybe it would have. There's really no way of knowing just what Philip Rivers would have done as a Giants quarterback or if he would have had anywhere close to the same success that Manning has had in New York. But, as it happened on that draft day back in 2004, the Giants quickly traded Rivers to San Diego for Eli Manning and the rest, as they say, is history.
