I know some people that only rely on odds and don't have any clue about the sport itself and I wonder if that way you can be any successful on mid/long-term, I only placed bets on a few occasions on teams/sports that I don't have any information on them and I lost on most of those bets so I can not possibly imagine how does that work out in such unpredictable sports like NBA and Soccer and because of that I just stick to teams that I know about their history and follow their news instead of betting on some random team winning or losing the match.
It is not easy to rely on the team's odds if we do not have much information about that team. They can beat the other team if the opponent can turn back and get more power from their player. But if we only use that bet for fun, that will be no problem as we do not chase for the winning, and we consider that we gamble with our money and hope we can win because of luck. You can win in that game, especially if you have luck, so you can continue to use that method and hope you will be lucky in the next match.
Exactly, lets suppose you want to bet on a match and then you find a team has an injured player, unless you know anything about the sport it is going got be impossible for you to tell if the injury was in an important player or if it was just a player that did not meant too much for the team, and even if you can read this on the news itself you will have to trust the source itself and this is not always the best thing, as we know there are many players in team sports that are not flashy but that are in fact the soul of the team and without them the team is not the same.
