The Cleveland Browns rebuilding methods and techniques of salary cap manipulation pioneered by Paul DePodesta and Sashi Brown (and now Andrew Berry) are becoming a league-wide fad. After watching the San Francisco 49ers copy the Browns methods last season and make it all the way to the Super Bowl by overspending the cap allowance, other teams are trying to do the same thing, although most are going to screw it up.
The upshot is that there are nineteen teams that need to either restructure huge contracts or cut some high placed veterans to squeeze under the regular season salary cap.
