I'm just gonna go through for ***** and giggles... going mostly by QB rating, and judging a QB as "top 10" when they put up multiple 90+ scores for multiple seasons
Russell Wilson - 1st season
Joe Flacco - n/a - Probably not considered "Top 10"
Eli Manning - n/a - Probably not considered "Top 10"
Aaron Rodgers - 4th season - looked pretty mediocre until the third season
Drew Brees - 4th season - looked pretty average his first starting season (2nd NFL season), was awful in his 2nd starting season (3rd NFL season) then something awakened in him his 3rd(4th)
Ben Roethlisberger - 1st season - Wasn't asked to do much, but finished with a high QB rating due to solid game management. Didn't really really "take over" until season 3
Peyton Manning - 2nd/6th season - his rookie campaign had the usual rookie inconsistencies, but he definitely showed promise. Didn't really start putting up gaudy QB rating until 6th season, though
Tom Brady - 5th season - First few seasons were definitely decent for a young guy at his draft position, but didn't really start taking off until around the 5th season
Brad Johnson - n/a - Probably not considered "Top 10"
Trent Dilfer - n/a - Probably not considered "Top 10"
Kurt Warner - 2nd* Season - Kurt had the benefit of 3 years of pro Arena experience after college. He got hot to start with, then had a few down years, then finished relatively strong.
Not gonna bother going too much further. Because in former years, it was tougher to get 90+ QB ratings.
Yes, I know this "study" is flawed... but I honestly feel our perception and expectations have changed because we have had Wilson and to a lesser extent Luck/Kaepernick/RGIII all show up as young/rookie QBs and be immediately successful. The truth is, it generally takes a QB time to find their footing in the NFL.
I want to clarify, I'm not suggesting that EJ is going to be good/great because of the above "findings" but rather I'm sticking with my opinion in that "I don't know" what he's going to be, and that he's showing me enough to let him develop for a couple years before I throw him away.
