The SuperBook on Saturday opened the Browns as +140 favorites to win the division, trailed closely by the Pittsburgh Steelers at +160 and Baltimore Ravens at +250.
The Westgate Las Vegas SuperBook has the Browns as a +140 favorite (bet $100 to win $140) to win their division in 2019. The Pittsburgh Steelers have the second-best odds to win the division at +160, followed by the Baltimore Ravens.
I have seen a number of blurbs like these above today. Apparently, since the Bengals opened at +2000 it's now a 3 team division.
