I need help on deciding on a trade.?

Are you serious? No way, you're getting ripped off badly. Sure you might be getting a top 5 outfielder in Holliday, but you're giving up two solid starters (Lee & Pence) and two solid bench guys (Kendrick & Burnett) in exchange for ONE elite player and three useless guys. Don't buy into the spring training success Rodriguez & Willis have had, they're still far from good fantasy players. Let's say if you're giving up Lee & Pence for just Holliday, you'd be giving up Kendrick & Burnett for those three guys, no way would I accept that.
