Reading this, honestly, I'd say the problem is you then?

Velocity is everything.

This is something even my manager wouldn’t say. I think he is feeling embarrassed from all the evidences. To be fair you didn’t read them. I agree that velocity is everything and as a manager they shouldn’t slow the team down.

I don't know what your evidence is, but I'm fairly sure I'm on the polar opposite. I see it working and it's the new norm.
