I know this is a little awkward since we're "competition" and such, but I had a few people who helped me last season when I was just starting out and I'm a big believer in "giving back what you get". If you have any questions or want any advice or anything, send me a PM and I'll be glad to help out.
And yes, the first roster you're given has a LOT of dead weight, so you're going to want to do a lot of rebuilding, lol.
