Corgan in Contradiction Shock

In an earlier interview, Corgan appeared to take credit for Jimmy Chamberlin's drumming style. "What???!!!11!111!???" indeed!
But, in another new interview he, again, talks a little about the formative moments of the band...

When we first started the Pumpkins and Jimmy Chamberlin joined and I realized he knew every Rush fill, I was like, 'OK. This is great.'. The prog element of the band is something that not everyone has understood, but Jimmy and I were both really into it.

So how much credit can you really take for influencing someone to play in a certain way, when, before they have even met you, they already know how to play like this?

Not that much.
