I know there must be a good reason LSH doesn't return punts but I hate Breaston as the punt return guy ..he just doesn't look interested in it anymore.
Different skill set. Its why Good Kickoff return men arent always good Punt return men and vice versa. Most teams have two different guys doing it and its rare to have a guy who can do both very well. For example, Percy Harvin is a really good kickoff return man but they wont let him return punts. Its becuase while Harvin is super fast he does have the wiggle that you need to return punts, he is a stright line runner. I think LSH is in that same category.
With Whis going to more 2 TE formations on offense, I favor keeping Steve Breaston on the PR man. He's reliable, seldom loses yardage, and is fearless. Yeah he sometimes foregoes a fair catch when he should make one, but I like and trust him back there. Normally it is best to have WR on punt returns because they are used to catching the ball.
