Peyton Manning is the most prolific passer in National Football League history. He's the career leader in passing yards and passing touchdowns, holds those single-season records, and holds numerous other accomplishments. It's possible that those and other records will be broken (and perhaps sooner rather than later), but there's one record that Manning doesn't think will ever be broken: his records with wide receiver Marvin Harrison.
Manning and Harrison formed the best passing duo in NFL history, finishing with the most yards and touchdowns between a quarterback and receiver ever. The two combined for 953 completions, 12,766 yards, and 112 touchdowns during their playing days together, and Mannign doesn't believe any duo will reach that touchdown mark.
"The very first preseason game, very first pass, I threw a five-yard touchdown pass, and Marvin Harrison ran 48 yards for a touchdown," Manning recalled during today's press conference with the Colts. "I was sort of thinking, ‘This NFL is easy. You just throw a short pass and Marvin Harrison runs for touchdowns.' Which is pretty much what he did for the entire time he and played together. I think many records will be broken - most of my records will be broken - I don't believe that record that me and Marvin have of throwing the most touchdowns together will ever be broken. Even though that was a preseason game, that was the first of many."
Even in today's passing league, Manning has a very good case to back up his claim. As Pro Football Talk points out, the duo with the second-most touchdowns is Steve Young and Jerry Rice with 92, while the closest active duo is Phillip Rivers and Antonio Gates with 76. Rivers and Gates will need 36 more touchdowns to pass Manning and Harrison, then, and considering the fact that Rivers will be 34 next season and Gates 36, it's certain they won't get to the Manning and Harrison level. So it's very possible that this record could stand for a long, long time, as we'd need to see a quarterback and receiver both play at a high level for such a long period of time. Manning and Harrison are two of the most consistently top-tier players at their respective positions in history, so it will be hard for someone to top their record. Only five players in league history have more than 112 receiving touchdowns period (one of them is Harrison), much less from one quarterback! Other quarterbacks may break Manning's records, but it may be quite a while before we see a duo break his records with Marvin Harrison.
