I don't think 3B really is that thin, there's just a dropoff from the top two or so and then it's kinda middling.
I like Middlebrooks more than I should, and Fenway is a good place for him to be but I'm really leery of wrist injuries and the long recovery time to get power back. His power is almost all of his value but I think it's really speculative to hope that he'll get it all back even by the end of this season.
I've seen him go as low as $14, but I'd put him more in the $16-18ish category.
I have him at 6th overall in AL only. I actually have guys like Seager & Machado ahead of him, but you could certainly make the case that he would be more valuable. He strikes out a lot more than you would want so he may struggle to keep the average up. I like the power a lot though. $18-22 seems about right.
Well, he is probably 5th at 3b so he does have value. $22 seems quite high for him though and $34 for longo seems like a great deal. Did you just have a draft? $260 cap? And yes 3b is extremely shallow. We have several players leaving the position (Bautista, EE, Trumbo) so if you can get a decent 3b that is an everyday starter, he is definitely valuable. In an Al/Nl league I would probably avoid him. I haven't read too many positives about him but Al only is a whole other story.
I would say $22 is on the high side for him, being from NE in my AL only, he would go for $25, unfortunatly, someone has him at $5 for a keeper. If 3B is thin in your league I would keep him. I would put Cabrera, Longoria, Lawrie and Beltre above him. That leaves Moose and maybe Youk.
