Dude, I like you and I dont want to laugh at you or insult you, but what you just typed there is kind of silly. You would know if you had some basic understanding of betting and probabilities but you clearly dont. I used that +3000 line for Glover by decision as a deliberate exaggeration, in reality it would never get even close to that and any booker making mistakes of that scale would be bankrupt fast, because in physical reality the probability of Glover winning by decision is so much higher than the +3000 line implies. And you just went and said that even that line would not be enough because "you have to be realistic"..
First of all, the fight is only 3 rounds, which already increases the probability of decision significantly. You said that there would have to be at least a "tiny chance" for Glover by decision to happen. You probably already know that you should not have said that. You are basically saying that there is not even a "tiny chance" that Glover Teixeira can win Anthony Johnson by a decision. If something seems very unlikely (in this case we are talking about 10-15% and the betting lines are going to imply that, Glover by decision will probably be around +600-+1000) it doesnt mean you have to go full retard and start talk about it like it is impossible to happen.
Glover beat Rampage by decision, in a 3 rounder, and it is actually a relatively similar match up. You know very well there are tons of possible scenarios how the fight can play out for Glover to win by a decision. Rumble might gas, they both might gas (USADA), they might clinch against the cage for long periods of time, Glover might be able to take Rumble down a couple of times here and there, etc, etc.
Im a fan of Rumble, but now I almost hope Glover would win a decision just so you could learn a lesson, lol.
Anyway, peace. Im going to bed.
Ps.And no, I did not mean at all that betting is about "getting those long odds". Just that if that example of +3000 line was real any +EV bettor would jerk off for that and they would heavily bet on that without even thinking about it.
