I would personally keep Kottaras. As a backup catcher, a left handed power stick with some plate discipline has been a rarity to say the least here in Milwaukee. So I'd argue that his bat is worth his roster spot. On the down side when he was given a shot to be the everyday catcher last season, his defense was U-G-L-Y !! Passed balls, wild pitches, and successful base stealers were the norm. Not that it counts for much, but he's looked better in his handful of games this season. But I don't think the Crew will go with George. I believe they want a veteran backstop to mentor LuCroy. I don't know. I guess Nieves may call a good game? Maybe he gives a good target? He's probably alright at blocking pitches. I'm just tired of Kieth Osik, Chad Moeller, Jason Kendall, and the like. But hopefully his 30 games will be won't cost the Brewers.
