Because he's not a perfect catcher. It's one of the few holes in his game, but frankly, there aren't many catchers out there who are good it catching for a knuckleballers. It's as niche of a skill as throwing one is. Being a good catcher is more than just keeping balls from getting to the backstop. And by and large, he still does many of those things very well. His offensive stats are virtually the same as Flores' but is better defensively. I've always been one to think that someone like that can really help a young player like Flores as he continues to develop. He'd also, I think help with a young pitching staff. He demands instant credibility and gives those pitchers confidence. One thing he also does is lend credibility to the organization with the fans. Most fans are going to recognize his name. IMO, I'd say the positives outweight the negatives assuming it'd only be for a couple of years.
