If they're useful, yes. If not, no.
I'd look into the future. If the pitcher(s) you seek can help you when you think you can compete, pay away. If not, bargain shop at the end of FA for 1-2 season deals with decent pitchers who will keep you in games.
Edit: To extend my thought, set a goal for your team. Something realistic. If it's "improve by 10 games"(which should be the minimum goal, IMO), make move that ensure you improve by 10 games at whatever cost. I've taken some "projects". I always set 1, 2 and 3 season goals. And I work towards them in season 1.
