How the Ravens Became Superior to the Steelers

I have been thinking alot about this lately. Just how and when did the Ravens start to surpass the Steelers as Kings of the AFC north.
I think it started with 2008 draft. While Baltimore added, Flacco, Ray Rice, we added Mendenhall and Limas Sweed. In 2009 it was slight advantage to Baltimore (Oher, Kruger and Webb vs Wallace, Keenan Lewis and Ziggy Hood) in 2010 The Steelers won the draft war with (Brown, Pouncey, Sanders, and Worilds vs. Pitta and Dickson), 2011 seems to be another Ravens win Torrey Smith vs. Cam Heyward, but too early to make a definitive judgment and in 2012 their rookies saw more time and arguably considered more than the Steelers did. So for four out of five years the Ravens drafted better. Plus two Steelers first round picks were spent at DE, a position where historically we have found guys late, who are specifically suited to be 3-4 ends so Heyward and Hood hurt badly.
Now comes free agency, and cutting the cord when time is appropriate. Since 2008, Baltimore let some players that still had productive potential go. They included: Ben Grubbs, Jarred Johnson, Willis Mcgahee, Todd Heap, Jared Gaither, Kelly Gregg, Cory Redding, Tom zbitkowski, Jim Leonhard, Chris Carr, Derek Mason etc. Where I feel that the Steelers messed up the past few years was keeping Farrior, Aaron Smith, Ward, too long. Not letting Hampton, maybe Harrison, Wallace, Mendenhall walk last year. MAJORLY they resigned WILLIE COLON, and Chris Kemoeautu two guys I feel Baltimore would have let walk the moment their contracts were up. The cap would have been a lot less tight had these guys who all produced less and less each year had been allowed to walk. Then the most unfortunate and least appealing question what is to be done with Troy Polamalu, is he now Bob Sanders? Once great, but can't remain healthy?
Let me clarify, you just don't cut just because age, Brett Keisel has kept producing, and Max Starks has been solid. But it just seems like from 2008 on we kept doing things the "Steeler Way" and then they started drafted poorly. What you happened was that a Super Bowl team became an eventual wildcard team and then an 8-8 team. They became old, slow and a team lacking impact play makers.
Finally in activeness in acquiring new players via free agency and trades. FIRST AS ALWAYS LET ME CLARIFY I AM NOT EXPECTING DANIEL SNYDER MOVES IN FREE AGENCY.
By trimming the fat the Ravens added Aquan Boldin, Vontea Leach, Bernard Pollard, Matt Birk, and Jocoby Jones. All players who contributed greatly to the Ravens playoff and Super Bowl run.
The Steelers during that time acquired Jericho Cotchery, Antwaan Randel-El, Larry Foote, Johnathan Scott, Leonard Pope, Arnez Battle, Will Allen, and maybe a couple of other guys I am forgetting. Compare the names, compare the contributions. Which list would you rather have?
So there it is, from 2008-2013 the Ravens have drafted better, utilized trades and free agency better and trimmed the fat better than the Steelers did. Is it any wonder one team is Super Bowl Champions and one team is mediocre looking for an identity The Steeler way (which has worked for years) didn't work this time.
Just my opinion.
