Parys Haralson isn't the best breakout candidate, considering he'll come in the 2013 NFL season as a situational rusher, unless injuries emerge, of course.
Some don't remember, but Haralson was the starter at OLB opposite Ahmad Brooks in 2011 before Aldon Smith took over towards the end of that season.
Now, Haralson was never a flashy player, but he proved effective as a run stopper and a speed rusher off the edge. He was a perfect situational rusher for the 49ers before an injury ended his hopes of duplicating another strong season in 2012.
With Haralson back in the fold in 2013, I expect him to be one of the best situational pass rushers in the league this season
Remember, the 49ers run defense struggled numerous times last season, even with the presence of a healthy Justin Smith.
Now, I directed most of the blame to the middle of that defense, but believe me, a healthy Parys Haralson coming off the edge will provide an instant edge to their run defense.
Even Jim Harbaugh and Vic Fangio agree that Haralson would have made an impact last season if he was available to play.
