At halftime of the Week 16 matchup between the Seattle Seahawks and Los Angeles Rams, LA led just 13-7. It felt much worse. Except for the first drive when the Rams went for it on 4th-and-short and failed, and the very last (and utterly meaningless) drive, the Rams had their way with Mike Macdonald's defense.
Macdonald, who is a very good head coach, and this is not meant to take anything away from that fact, was hired by the Seahawks because his predecessor, Pete Carroll, no longer could produce defenses that could consistently slow the Rams or the San Francisco 49ers.
