Trent threw for more yards per game, threw for a better yards per attempt (which directly refutes your theory that Trent had the high completion percentage because he threw shorter passes), had a higher completion percentage, had a higher QB rating, took less sacks, and fumbled fewer times. All of those statistics are relatively close, but you simply cannot use them to say Flacco had a flat-out better season. You honestly want to tell me that Trent couldn't have led the Ravens to the playoffs?
