I feel like if we can't develop McGroarty then we have no business trading him for a d-man with even bigger issues.
Columbus isn't exactly good *or* deep on defense and if even they see Jiricek's issues as too big to fix then he's not going to get anywhere here.
McGroarty was appealing, I think, because he was also quite safe. Good size, somewhat mature game in all zones. The offense may or may not come but all signs prior to the trade suggested his offense was as likely to translate as any other prospect that might've been available, and more than Yager probably.
