Can someone explain this to me

[Jwilzzz]

I know it's only preseason, but I've seen this before
The colts against st Louis are -1, yet on the moneyline are +105

Ive always wondered this myself but I believe it's because over 60% of the public is on the Rams Spread and they dont want to move the spread off of 1 so they just jack up the ML. Colts opened @ 2.5.Could be wrong though...
