Or just train more efficiently. It has already been said that multi-skilled players will have lower salaries. So go that route. If a player starts to be unaffordable, sell him and improve your team in other areas.
By the way - I don't think one 70k player would bankrupt a division I team. Having 5 starters with that salary is another story. I personally would go for more balance than one star but other teams feel differently.
Last thing - 10k for a player is peanuts given that you get TV game revenue 3 times a season and playoff revenue. I know finances are tough at the beginning but eventually things will change for you.
