Is this profitable?

[TheRover]

I decided to bet every college game off .5 or more of the common line that was available to me.

Anything that was available at four or less books listed here I considered "off". No handicapping the games themselves involved at all.

Example: NC-Greensboro were +6/+6.5 at most places except sportingbetusa.com where it was +7. So I bet it even though I don't know anything at all about either team.

I was going to do this myself, but I might as well save my money and ask you guys.

+EV?

Should I limit it to 1 pt. or more off?

thoughts?
