Blitzball is the equivalent of having gas soaked shards of glass shoved up your anus then lit on fire.
What pisses me off is you simply cannot win. The game sets you up to fail.
This is my sixth time playing through FFX. I've already played the blitzball game four times today. It is physically impossible to win.
I cannot keep control of the ball. I never steal from the opposing team in tackles yet they always steal from me. 100% of the time.
I even went through the tutorial again today to see if I was doing anything wrong.
Nope. The game just fucks you over.
Are you talking about the Championship match?
Because I beat that on my second try, both times having been derpy enough to fail to remember you have to press Triangle in order to enable manual movement. So I was letting the AI pretty much make all the moves (sans Passing and Shooting triggers) and still pulled it off, despite the bone-headed 'zerg rush' tactics the game uses on full auto.
Just try a hot-potato tactic and avoid contact with the enemy as much as you can until you can get Tidus in for a Jecht Shot. Take long range passes to backline members if you have in order to avoid being boxed in.
And if you really, really don't want to play fair. You can always Jecht Shot at range, score, then pass the ball to someone and hide in your own goal the rest of the game (assuming they didn't fix that, I haven't tried yet).
If you mean the rest of Blitzball; wait til end game, recruit better players, play Exhibition mode only for a while and pass the ball to everyone on your team. Also allow the enemy to take a few shots at your goalie.
You need to start hitting the 10's before more of the better stat curves for your players start kicking in.
