They are actually not 1-2 according to those odds.
Looks like they think Chicago is going Levshunov and Silayev going 3rd.
Off course, odds will change with the more info they get, but that what's betting sites are....ALL the infos you can get and interpret it mathematically, not with a confirmation bias approach which 99.9% of the Fans does, me included. They have mathematical info about people betting on their site too and sometimes, they have good info. They see the swings before we do.
There's a reason that right now there's nothing available for 4th overall pick but have the option for 5th overall.....once they have a more solid info, they will get it out.
