Why do you quote two Red Sox employees to support your argument? Do you expect them to give a negative report on Brentz? I don't look at baseball reference, I read scouting reports, and here's one from Matt Sullivan of fangraphs.com
Maybe he becomes another Middlebrooks, but Middlebrooks destroyed AAA pitching for a few months before he was called up. It's an awfully risky proposition to have him rushed immediately to the bigs. Let's see what he can do at Pawtucket first. Although, I would use him as a trade chip.

This is how he stacks up with other 25 year old 1B with 1200 AB's. It's an awfully big gamble to suggest that it's just Safeco robbing his power. At least, Beltre had a track record and the physical strength to suggest otherwise. Smoak has never hit big league pitching.
OK, but you keep penciling him in for his AAA numbers. I'm saying that's too hasty and that we should have another option in case he fails.
He's a young left hander with good stuff, who had a lower ERA in a tougher league, and a more hitter friendly ballpark. He's being paid the minimum. Factor all that in, and he's a lot more valuable than a pitcher coming off a horrible season. Another worrying issue is that his velocity is down, and his pitches don't look as a sharp.
Also, Barry Zito is starting over him.
I don't care. The Rockies would never do this deal. Not in a million years.
