I'm down with this! I would prefer that he avoid big hits, and run out of bounds instead of trying to lay a hit on someone. People used to bitch about Shaun Alexander doing that, but there's no sense in getting hurt trying to prove a point.
Chris Carson was a Monster when it came to plowing in to people, especially along the boundary. Pete Carroll kept telling him to stop hitting people at the end of his runs, but Chris couldn't pull back, and it shortened his career dramatically.
Same thing for Jaxson Dart, whose running style has knocked him out of games.
I LOVE that JSN avoids hits as best as possible. He's not built to take on 200# plus linebackers, and DBs.
So sign me up for retaining K9, because next years offensive line will be so much better than this years because of the experience they got playing together this year, as well as learning Koobs' blocking scheme.
