I do think that Tressel has some problems in big games, but since 2005 he has only lost to teams who played in BCS Bowls (2005 - PSU, Texas; 2006 - Florida; 2007 - Illinois, LSU; 2008 -USC). Three out of those six were National Champs (and USC is a potential fourth). USC has lost to Oregon State twice, UCLA, and Stanford in that time. Oklahoma has lost to Colorado, TTU twice , TCU, and UCLA. LSU has lost to Kentucky and Arkansas. While OSU chokes in big games, they still get to them and they beat the teams they should beat.
