and you came up with 2.1 how exactly? you can't just pull a number out of the fukking air. no way in hell you capped that number yourself.
and if you forecast the sack total at 2.1, then the fair value of Over 2.5 should be +165, instead it is -145. so you could have the Under 2.5 for +115 instead of the -185 that it should be.
