Question to SR Who Dats: Vitt and Spags?

We all know that Vitt is family to SP. Vitt was willing to take the sword over Vicodin-gate. He held the team together while SP was gone this year. Vitt is possibly a pretty weak LB coach, but SP will stick with him to hell and back.

Did anybody hear from any semi-reliable source about the relationship between Viit and Spags? Was there friction? This alone would have been enough for SP to can Spags.

Thanks Who Dats!
