MLF has had live tackling periods in camp at least twice so far, don't think he did that at all last year.
After last year, they need the practice at tackling.

The NFLPA has strict guidelines on certain practices and timing, which is good to protect the players, but it does feel like it overreaches at times. (Easy for me to say, I'm not in camp.) As much as I think a little 'toughening' would do them some good, I'd hate for them to get to Week 1 feeling beat up or fatigued from a grueling camp. It's a long season and 300 pound people running full speed into each other takes a heavy physical toll.
