I think the notion that it was Lamar's fault for all of the pass plays comes from a Harbaugh statement soon after the AFCC loss. He said something to the effect that many of the plays were designed to go pass or run depending on what Lamar saw at the line of scrimmage. Unless someone from the Ravens wants to break down how many run first plays were switched by Lamar to pass, we can really never know whether it was in Monken's game plan to run first and Lamar changed it many times, or it was Lamar simply going with a pass heavy game plan. But Harbaugh's statement was in response to why more running plays weren't called so if the game plan had a pass heavy look then he threw Lamar under the bus by implying that it was his option to call run or pass at the line of scrimmage.
As for the label that Lamar can't win the big one, it might not be fair but that stigma will follow him until he does. It followed Peyton in his early years until he won the SB. It followed Elway for most of his career until he broke through. It followed coaches like Andy Reid, Bill Cowher, and Don Shula until they won the big one. It's the nature of sports and it's amplified in this era of big mega-contracts for QBs.
