It's really hard to compare Lamar to older Quarterbacks because the NFL is so different.
Like Joe was an above average regular season QB who had high highs and low lows. His best attribute was playing really clutch in the playoffs. During that era of the NFL (literally over a decade ago) defense was what won championships. So Joe really took advantage of our strong defense and running game and played lights out as QB. His historic performances that postseason is a huge reason we won the SB.
In Lamar's Era it's really different. Lamar is a tremendously better regular season QB compared to Flacco, but he's not been as good in the post season. I think it's fair to say that there's been a shift to defenses win championships to offenses win championships. With that being said, if Lamar wants to continue to build his resume so that one day he's in the HOF, he's gotta just totally become the guy that runs an offense capable of beating even the best teams.
The awesome part is he's never looked more up to that task than he has so far this year. And imagine if we can get some help from Stanley, JK, Gus, Kolar, Boyle, and Proche to add to what's he's already been doing.
