Can I win a championship with this fantasy basketball team?

Well, you have strength in some categories (Rebounds, blocks and 3's), but your also weak in some categories (ists and steals). If you're in second place at this point your team is probably pretty good, but without being able to see the other teams it's hard to say that you'll win it all. Best strategy at this point is to look at the team that's in first and third and find out where they are strong and weak and make sure that you are competitive in the categories that they are strong in and exploit their weaknesses by being stronger than they are in those categories. Good Luck!
