When the hit on San Diego Chargers receiver Mike Willie occurred, the first reaction was that rookie Jonathan Bostic had just showed the kind of closing speed that was behind the Bears using a second-round draft pick on the Florida linebacker.
The second reaction was that Bostic may well get an unpleasant notification from the NFL that the hit was illegal and would draw a fine. That letter arrived for Bostic, fining him $21,000 for lowering his head delivering the hit.

It wasn’t a violation under the “crown of the helmet” rule being brought in this year. Instead, under Rule 12, Section 2, Article 7 (b) (2), it is prohibited to lower the head and make “forcible contact” with the top or crown or forehead parts of the helmet against any part of a defenseless player’s body.
Bostic already has a defender. Linebacker Lance Briggs tweeted Wednesday morning:
