I would think that Lofton would have an easier time in the 3-4, seeing as how he would have less coverage assignments...

The SOLB will be in charge of the outside of the TE on running plays and will normally either blitz or be manned up on the TE in pass plays.

The SILB will blitz around 20-25% of the time on pass plays but normally cover an underneath zone, while in the run game is only responsible for the strong-side "B"-gap.

The WILB is covering the middle of the field in a zone on pass plays usually and will be blitzing only about 5-10% of the time. His job in the run game is to be the only guy covering 2 gaps. He is responsible for both the "A" gap in the run game, as well as cleaning up the "B"-gap if the DE decides to go to the outside shoulder of the OT in the run game.

The WOLB's job is to take care of the weak-outside, and is normally the best pass rusher on the team. He will normally be the guy who will be making the most sacks, and blitzes over 50% of the time in the passing game.
