Some mid to late round guys you could consider targeting:
Loney (not the next Howard, but still can provide good value)
Zimmerman (not mid-round really, but if you miss out on the top 6, not a bad alternative)
Griffey (still decent numbers when healthy)
Fukudome (Japanese hitters can be a crapshoot, but worth a gamble imo if he falls far enough)
Willy Mo Pena
Well that's just like, your opinion man.
