Julius Peppers: Really Good Article

[mraynrand]

I thought losing contain meant being the last guy on the edge and letting the play go outside of you.

yeah, but on some plays the guy rushing from the edge may not have 'edge' responsibility. Another inside guy has that responsibility - he 'spills' outside.

(edit: perhaps there's a confusion of terms, which I didn't help. The inside guy going outside is a 'scrape' not a 'spill.' whatever the terms, if Peppers' assignment is to crash inside, someone else will have the outside contain)
