I don't know why so many people dislike the guy. Is he one of the greatest playing today or ever? No on both counts, but he's really good. The Ravens have a very nice team and Flacco is coming into his own, so yeah - he's going to get paid and he's earned it.
5 years in the league and 5 trips to the playoffs.
54-26 as a starter in the regular season.
8-4 playoff record. Lost the AFCW Title game in 2011, won it in 2012.
The guy has played really well and has some things to accomplish before he approaches Eli and Ben status, but he is far from horrible.
