Romo played 10.5 games and put up some of the best passing numbers in the league. He ranked No. 1 in yards per attempt, No. 1 in average yards at catch (the length of the pass thrown), No. 1 in percentage of passes thrown more than 20 yards, No. 2 in TD percentage, No. 2 in completion percentage, No. 2 in third-down passer rating, No. 3 in overall first-down percentage and No. 5 in overall passer rating.
He still has to prove that he can do the same things over a longer period of time, but he absolutely played very well last season. It's not like he was getting the hype without doing anything.
