Not necessarily perfect, just don't walk anybody. Then again, Lou hasn't exactly been consistent with his first impressions. I'm pretty sure Grabow walked the first guy he saw as a Cub yet he maintained a relatively safe position ever since (at least until now). You can give up hits and he won't kill you, see Howry. And for some reason Samardzija keeps getting chance after chance despite sucking hard (although I don't believe he walked the first guy he saw). The common line between Grabow and Howry is that Lou always seems to have some veteran he inexplicably trusts too much in the bullpen regardless of how bad they stink. Their "veteran-ness" wins out with him. I have little doubt that Hendry has at least implied very strongly that Shark needs to get innings, and Lou's response seems to be as petulant about it as possible to the point of putting him out there at the wrong times and leaving him out there too long. I think Howry's faith was about a lack of walks. While Grabow's was about sticking with the guy they went through the effort of acquiring. Samardzija's situation is complicated, but Hendry could always demote him, and he could do the same with Cashner if he got called up and not used. The concerns about usage are legit, but the solution is really easy if it comes to that. Bottom line is I would not have a problem with Cashner being called up to the bullpen, if he gets work. Samardzija needed work just to figure out how to get people out to begin with, at any level. Cashner is just about getting innings logged.
