A couple of years ago we spent nearly a $100 million on our OL too and look where it got us.
Anyways, I don't think Peter's replacement is going to play any worse than he did last year. Remember, he gave up 11 sacks, some of which lead to costly fumbles. If his replacement gives up less sacks that lead to fumbles, I say we improved. That said, Peter's has tons of potential and could have played much better last year. He purposely dogged it and if he was going to have a repeat season, then we don't need him around. Apparently, if a player wants a better contract and/or force a trade, they just have to stink it up one season.
