Indianapolis Colts fans all saw it in Week 15. The recently unretired Philip Rivers hadn't played in five years, had practiced for only three days, and was thrust into the environment of playing against one of the better defenses in the NFL. The Seattle Seahawks are no joke, but Rivers kept the game close.
The truth is, though, that it is clear Rivers doesn't have the arm strength now to push a ball 50 yards down the field cleanly. He also has admittedly never moved well and isn't going to outrun anyone. He's smarter than nearly any other quarterback ever, but that only gets an offense so far.
