You need to win 7 of the first 9 games to reach the 10th game for the achievement (which will unlock after the final game.
Here are some tips and hits to getting there,
you have ten players to put in your LU, and you get to pick one each time,
I put 1 Dominate dunker (MJ or Penny) and then 9 Tall shot blocking rebounders.
the first game is more about winning with your weakest link (ie the guard) i do this bcause its a faster game.. if you win you keep going if not just reset.
Now once you start using Center and PFs, here is the key, no matter who you get on your team, YOur biggest guy is who you will control on defense, basically just hover in the paint and swivel around to keep them from scoring inside, no matter what, if you keep them from scoring inside you will be successful.
on offense, feed that paint and try to get easy buckets or short jumpers, games 2-6 you want guys like Shaq, Mutumbo, CUZ, AD, Whiteside, (i also used sam Bullar)
When it comes to games 7-9 you want your more atheletic shooting bigs (dirk, Jerry Lucas are great jumpshot bigs.
If at any time you go up against a team that gets a Diamond Kareem, Foul that kid every time kareem gets the ball. when hes on offense deny kareem the ball the best you can, its very difficult to beat someone who has kareem unless you ave a great outside shooter, (keep in mind you def need a good inside defender if this happens.
If you get diamond kareem, feed that guy all day and twice on sunday.
in my first run through i went against kareem 3 times, managed to win 2 of the 3.. and that got me to my 10th game.
Dont freak out when the opposing team has a Curry or Lebron or Brow on their team, most of the people try to do to much with their best player, and are easily dismantled.. they will at best go 4-9 from 3 in most cases. as the mechanics for hitting 3s are less than consistant -- when this occurs you want to keep going inside for easy baskets, dont start jacking 3s trying to keep up. just go inside, they will miss enough 3s to keep you in the game if you score 65 percent of the time
GO inside on offense, easy baskets, pass the ball, dont dribble too much. Zone D.. dont let their bigs get easy buckets,
Only take 3s if their wide open from the sideline, that three has the best odds of going in of all the potential shots. ( dont take if it there isnt a big inside to get a offensive rebound if you miss)
following this should give you a good chance to make it to game ten!
