I know nothing about this matchup other than Messi desperately needs a big win and a trophy on his mantle. I just saw a prop bet in which Lionel Messi to score a goal and Argentina to win is +125.
+125????
Are you kidding me? This sounds like free money to me, which is why I'm pretty sure it won't hit. Assuming Messi scores at least one goal, which I would think is as close to a sure thing as you'll get in this match, I would then presume that the U.S. somehow beats Argentina.
Honestly, I can't see why anyone with this +125 prop available would bet Argentina to advance instead of this. I think it smells bad. Just my two cents.
