I like Teixeira/Young...Teixeira is 30HR-100RBI every season and plays in a left side hitting band box...Tex has been working twice as much on his left sided hitting this spring and should improve from that side...I'm not taking anything away from Prince, but Tex is a switch hitting beast!
If it's a non-keeper situation, i'd take Fielder and Stubbs, namely cuz of Fielder's contract year and the fact he's going to want to showcase the goods. Otherwise, for the long term I don't tend to trust fat guys.
If it's a keeper, i'd go with Teixeira and Stubbs... I like Stubbs over Young cuz Young has showed some wild fluctuations and sure he could be a 30/30 guy, if not a 20/20 guy, but your batting average will take a hit... granted, Stubbs wasn't setting the world on fire early last year, but he picked up the pace after having an awful average early... I'd go with him there.
