Remembering that players didn't come back as good as they were before is a confirmation bias. We want to believe that those that come back don't play as well, so we forget the ones that do. For every Kenton Keith and Casey Printers, there is a Henry Burris and a Ricky Ray and a Dave Dickenson and an Arland Bruce.
I also don't agree that Fantuz was worse. He didn't play up to his 2010 self, but if you look at his numbers, that season was an outlier and his numbers in 2012 were pretty much in line with his career averages.
As far as Chick goes, not sure if I'd make a play for him. Pretty sure he'd be looking for good coin and I think the Cats would do well to stick with the guys they have now. I want to see what Peguese can do with a full season and camp. I don't think he'd be worth the money.
