In order for you to succeed you must follow my steps.
Step 1:
Come up with a clever name. My name was Smoak on the Water, and my tagline was Fiers in the sky. I love puns. Half the fun of a fantasy league is coming up with your fantasy name.
Step 2:
Don't prepare at all. Write down maybe one player you really like even if they aren't starters or have a dismal batting average. For example, I drafted Danny Espinosa #1 overall because he is #1 in my heart and I had a paranoid thought that he'd be taken. It is always the best plan of action to pick your favorite player first in order to secure them.
Step 3:
Sign into the draft a half hour early and talk trash. You know you're better than all the others, so make sure they do too. Be sure to let them know that you intend to wipe the floor with them.
Step 4:
Draft just by picking your favorite players only and insulting anyone who laughs at you. What do they know anyway?
Step 5:
Obsess over your fantasy team for half a month until you realize there's literally nothing to do. Finish in #14th.
Congratulations.
Oh, if you actually want to win I can't help with that. I don't know how to win.
