"The linebacker has to make multiple, multiple decisions on every play. Not only what his assignment is and what the play is, but all the way along the line, different angles, how to take on blocks, how to tackle, the leverage to play with, the angle to run to and so forth, the technique. So many different things happen in a split second during the course of the play, just like it is for a quarterback. The more of those things that you can do right, slow down, get the most important things, not get distracted by all the stuff that's happening, but just really zero in on a target."
