I was debating with a friend of mine the other day and we had a pretty interesting topic. What if the Colts had Johnny Unitas, Peyton Manning and Andrew Luck in the prime of their careers, all on the roster at the same time? Who would be where on the depth chart, I argued that Manning would be the starter simply because he is Peyton Manning and with 59,487 career passing yards and 436 TDs so far, I can't see the Goat backing up anybody. My friend stated that the era Unitas played in put him ahead of Manning because 40,239 career pashing yards and 290 career TDs was unheard of at that time and that Unitas was the "Original Manning". Just to throw a wrench into our debate lets point out that Andrew Luck through 1 season is ahead of both Unitas and Manning. So I ask you fellow Colts fans to play tie breaker and end our discussion! In what order do Unitas, Manning and Luck rank as great Colts QBs?
