During the SB bye week, there were already articles citing Competition Committee members saying they'd crackdown in the offseason, specifically because of Seattle. They're dirty thugs; that's why they had MULTIPLE players whine their way out of yet more PED suspensions last year, and why the NFL's fined them two years running for making no-contact practices into yes-contact practices. Once the season starts, they'll go right back to practices with WRs wearing armor over all the legal areas so their DBs can practice legally rupturing organs and breaking bones.
Here's the best part though: All that got them to a Super Bowl where they humiliated historys best passing game for a full 60 minutes en route to the franchises first championship.
In other words, it worked; it won them the uncoveted Al Davis Memorial Award for most penalties in a season, but also won them a title, so you can bet all 31 other teams will shamelessly copy that winning formula as they do every time someone comes up with something new that works. Not that steroids and cheap shots are exactly NEW, but Seattle's made a systematic science of doing both in ways just close enough to legal that the division titles and Rings far outweight the flags, non-suspensions and token fines; it's fine as long as concussion-free.
