Tebow took a 1 and 4 team to the second round of the play offs. I can show you a dozen quarterbacks in the NFL that have NOT come anywhere near that record.
Also, Manning lost in the second round of the playoffs his first year with Denver. You could say he got as far as Tebow.
He had the help of a 1000+ yard RB (and 3 OT wins on Matt Prater's leg) - and lost 4 of his last 5 starts once opposing Ds figured out how to play him. What he did that year was an accomplishment - but it's far from proving that anything but his own limitations has held him back since then.
Manning lost in the 3rd round. Manning lead Bronco’s didn’t have to play in the 1st round so his 1-1 was 2nd and 3rd round not 1st and 2nd. So no, he got further.
And has never been forgiven for it.
