WHAT KIND OF **** IS THIS YAHOO I CANT PICK UP A PLAYER FOR TOMORROW? I THOUGHT I WOULD JOIN A LEAGUE AGAIN AND GET BACK TO FANTASY BASEBALL BECAUSE IM COMPETITIVE AS **** ONLY FIND OUT I HAVE TO BE A PASSIVE PLAYER. YOU RUINED FANTASY SPORTS. IVE BEEN PLAYING FANTASY SPORTS LONG BEFORE PEOPLE HAD THE INTERNET AND WHEN YAHOO FANTASY BASEBALL CAME ALONG I LOVED IT. AFTER TAKING TEN YEARS OFF I JOINED A LEAGUE. NOW IM TRYING TO MANAGE MY TEAM BECAUSE I MANAGE 24 7 AND FIND OUT I HAVE TO BE A PASSIVE MANAGER AND NOT A ROUND THE CLOCK MANAGER. THIS SUCKS I WILL PROBABLY LOSE INTEREST IN THE NEW LEAGUE. I JOINED BECAUSE THEY DIDNT PUT A LIMIT ON MOVES WHICH YAHOO DID TO APPEASE ALL THE WHINEY ******* WHO COMPLAINED ABOUT PEOPLE WHO MANAGE THEIR TEAM TO THE FULLEST. I JOINED THIS NEW LEAGUE AND FOUND YAHOO WONT LET ME MAKE ROSTER MOVES THE NIGHT BEFORE. THIS IS TOTAL ****. YOU RUINED THE FANTASY BASEBALL EXPERIENCE. I JUST CANT DO IT ANYMORE. YAHOO FANTASY BASEBALL USED TO BE THE THING I LIVED FOR NOW I FIND THAT ALL THE RULE CHANGES AND RESTRICTIONS MAKE IT A GAME I CAN DO WITHOUT. ITS TIME ILL NEVER GET BACK. NOT ONLY ARE COMMISSIONERS RUINING SPORTS YAHOO IS RUINING FANTASY SPORTS. I MIGHT CONTINUE IN THIS NEW LEAGUE BUT THEN AGAIN I MIGHT JUST ABANDON THE LEAGUE ALL TOGETHER AND LET THE TEAM RUN ON AUTOPILOT AND NOT WASTE ANYMORE TIME. YAHOO ISNT WHAT IT WAS IT JUST KEEPS GETTING WORSE. I GOT ALL MY FRIENDS TO JOIN YAHOO TO PLAY FANTASY BASEBALL. YAHOO WAS ONCE GREAT IT ISNT ANYMORE.
