I'd actually agree with you until the new rules were released that hurt DBs with an increase in PIs and the "hitting a defenseless receiver" nonsense that can occur for perfectly legal hits. Not turn your head in time while covering a guy on a deep play? Possible 20+ yards allowed on an innocent mistake. QBs might be the most pressured but I'd say CB has become the new hardest position in the league and I think that's true even in the playoffs.It is most difficult to perform at the QB position during the playoffs and in the biggest game of them all. The best QB's take their team all the way.
Not even all of those guys you listed were "extraordinary" QBs like I'd consider Peyton or Brady. Favre choked away too many football games with crucial interceptions near the end of regulation. Aikman wasn't bad at all but very fortunate to have that Oline, the all time leader in rushing yards, and Michael Irvin on the same team. Call me nuts but I think Eli is better than those two for sure and if Eli gets another SB victory, debate will rage if he is better than Montana (which is actually arguable now since Eli doesn't benefit from a WC Offense.)Heck, look at the last 20 years. Steve Young, Brett Favre, Troy Aikman, Joe Montana, John Elway.... It is no fluke that it happens this way.
To clarify, I put more weight on play-by-play basis and consistency which Eli doesn't measure up to Peyton or Brady in that regard. He has had some pretty legendary moments but some equally WTF plays as well lol.
