I don't know how to fix the Yankees so I'll just throw out some blueprints
1. Call up Sean Henn, and use him for mop up roles. That way you'd get his feet wet, and he could adjust to being in the big leagues.
2. Cut Buddy Groom, and trade for Seattle lefty Ron Villone.
3. Keep Bubba Crosby in CF, whatever he does offensively is a bonus.
4. Try to find a starter, maybe some like Mark Redman, if it doesn't cost the Yankees Duncan or Hughes, any other minor leaguers is expendable, (because Duncan and Hughes are the only prospects that have any talent at all)
5. Whenever Kevin Brown pitches, start Tony Womack at 2nd, DH Robinson Cano, and play Giambi at 1st. (Womack would help Brown, because he's much better defensively that Cano) Brown pitches for contact now, and needs some help.
