Just to clear a few things up
1) I've no idea if the LVH contest is +EV or not but my insticnt lead me to believe it if if you're using optimum strategy and game theory
2) I'm not changing my outlook by looking to enetr a contest based on opinion because its not really opinion. I would consult with people who have knowledge on NFL and factor in what way I think the lines are moving to make my plays. I wouldn't make a pick because I 'fancy' a side
3) A question: Lets say that every week if you grade each line on the LVH sheet in order of far it beat closer how many enteries would you think would have the top 5? Again I've no idea the answer to this question but if you could get as many of these amongst you entries then you'd have a theoretical edge over a chunk of the field.
I've no problem with being proved wrong on any of the above as I wouldn't be looking to discuss this if I knew the answers!
