Two words why Wade Smith looked bad last year: BRIAN GRIESE!
He looked like a premium tackle in the league until Griese, with his drops that were WAY too deep, and his complete lack of pocket awareness, entered the game.
Wade Smith's two biggest assets were he didn't get beat to the INSIDE, and he had a very quick and strong punch to send the pass-rusher around the backside of the pocket, and enough recovery speed to get in the way of the rusher and stop him before he could come up from behind.
With Griese the rusher didn't HAVE TO come up from behind, because he would just stand there like a sitting duck 11-15 yards behind the line of scrimmage.
Wade Smith has to work on his strength to get more push in the running game, and hopefully he can work on making his first step quicker, so he can tie up the faster DE's earlier. But, even if he keeps his skills the SAME as they were last year, he will not give up a lot of sacks with Feeley or Fiedler, because they both have short drops and more importantly understand the concept of STEPPING UP, unlike Griese.
