I recall saying that Manning should have gone to either the Seahawks or the Niners solely because of their defenses overwhelming ability. those teams with Manning would have no doubt won the superbowl(if Manning stays healthy) in my mind.
Yeah I really expected Peyton to go to San Francisco. Hell of a schmooze job by John Elway to get Peyton to choose Denver. Or maybe Peyton just didn't want to play in San Francisco for personal reasons, who knows.
I don't know about Seattle but the 49ers definitely would have been favorites with Manning once it was clear he could still play at a high level.
