I've had a soft spot for Brecht for awhile, and he makes for an intriguing underslot candidate, but he brings a lot of risk to the table as a guy with command/control issues, an undeveloped third pitch, and also coming from a program that's not known for developing and producing high end pitchers. Iowa also apparently mucked with his mechanics, meaning he's basically a teardown/rebuild type. You run a very real risk that he never makes the majors.
I'd be excited if the Cubs took him, but he's got a ton of work to do.
