Hey dback, welcome to BB. As a newbie, i definitely suggest going through not only the tutorials and rules, but also some of the discussion boards in order to see what other, more experienced players are doing.
Just a couple of tidbits from what I remember/regret from when I started:
1) Clear out any junk you have in your roster. fire any old players that dont have any reasonably good skill and any young players with a potential of 6th man or lower. This will not only allow you to focus on training your future stars, but also decrease the amount of salary you have to pay. ( The salary floor doesn't apply to you in your first season) Remember, money is king in this game.
2) Acquire a decent trainer, and train only your young players. At the beginning, an advanced trainer will be all you need, as higher level trainers are expensive to not only hire, but also keep. And keep in mind that the older a player gets, the less he win respond to training, and training a player beyond the age of 26 or 27 is a waste of precious training time. And most importantly make sure your trainees get at least 48 mins of training time each week.
3) Acquire your future stars, either through the draft or free agency. The lower your record during the season, the better pick you will have during the draft, and a season like this season, where you might end up getting a top 3 pick, might land your stud. However some claim that the draft is too unpredictable, and there is no guarantee that your #1 pick wont be the future waterboy. Personally, I prefer to get my trainees through the transfer list. It might be more expensive, but at least you know exactly what your getting, and you don't need to tank in order to get a good trainee. But I'll let you decide what you wish to do.
4) Bring in talent where you need it. The most amount of players you can train effectively each week is 3-6, so you will need to fill gaps in your roster through other methods beside training. Older players are not only relatively cheap to acquire past the age of 32, but they can make an immediate impact and bring experience to your team. Be careful not too load up on veteran players however, as this will cause you to be really good quicker, but you will either drop off into terribleness when they get old or bankrupt your team trying to bring in more players. You need only to compliment your core talent.
5) Get through the growing pains. you will lose a lot this season, and probably next season too. but gradually building your roster through smart training and tranfers when necessary is the best way to have success in the future. Be careful with your money and your players.
I hope I can help in anyway, other than telling you how ill beat you in our upcoming matchups :) Good luck
