We entered Week 3 with seven undefeated teams in the NFL; we leave with three.

Many teams were put on notice in Week 3, while others were exposed a bit. Most people knew the Houston Texans weren't a true contender, despite their 2-0 record, and we saw that Sunday with their struggles against the previously winless New York Giants.

The stories of the week, though, may be the embarrassing defeats suffered by the Tampa Bay Buccaneers (56-14 loss to the Atlanta Falcons) and the Jacksonville Jaguars (44-17 loss to the Indianapolis Colts). Much was learned in Week 3, and the writing on the wall says these two teams are at the bottom of the league right now.
