I don't even consult this kind of sites when I bet on sports. Scores are just numbers, what will give you the best guide or reference for your analysis is your knowledge about the sport, teams, team advantages and weakness, and their edge among other teams.
You said it right, those news is basis but it's better to have a good knowledge with the types of games that you are going to play, if you have a good understanding regarding to the match you can simply analyze the possible outcome, news will help you to pick the team/players which have soe good advantages.
