For me, and my opinion, betting either high priced favorites or dogs is burning money. Yes you will no doubt hit a string if winners on the favorite side but no doubt, you will get smashed on that one game. Same on betting high priced dogs, you will lose and lose and lose, then may make it up on that one win.
I think the only spot to play money line is on the plus side of line 2.5 or less and the only time to play the favorite is the Super Bowl as usually there is value on the money line for say a 7 point favorite (money line is usually about -240 when it should be 280 to 300).
Speaking football here and from a long term and serious perspective. For sure there are party nights where I take a plus 500 for shits and giggles but that IOC course is just for fun.
Lastly, parlaying huge money line favorites is not 'getting around it'. I have read several times how parlaying favorites is doing just that. Even read how using a -1000 favorite in a parlay with your straight bet is getting around the vig. It's just not so.
now, I have used -5000 favorites to parlay with my straight bet, as a second bet, to circumvent maximums. And yes. Have gotten stung with that on one occasion.
