At 4-0, the Los Angeles Rams are one of two teams still unbeaten in the NFL, and they're the betting favorites to win Super Bowl LIII heading into Week 5.
According to OddsShark, the Rams are +333 to win a title in 2019. Somewhat surprisingly, the 2-2 New England Patriots—not the undefeated Kansas City Chiefs—boast the best odds in the AFC. The Patriots are +700, with the Chiefs following closely behind at +750.
The Baltimore Ravens and Philadelphia Eagles are both at +1,600 but are trending in opposite directions. The Ravens are coming off wins over the Denver Broncos and Pittsburgh Steelers, while the Eagles lost 26-23 in overtime to the Tennessee Titans to fall to 2-2.
