"Nowadays the whole bet dogs late, favorites early theory is crap": this is something I fall into the trap of. A few guys talked about the last few years this has been the complete opposite. The old days it was if you like a favorite a lot you bet them early in the week but now they say there were a ton of times last year in the NFL when you should bet the favorite as late as you can as the number will keep going down right until kickoff.
I think this is pure BS, and I can back it up with my records. Faves still get bet early and dogs late. Happens all the time every year.
