It is a matter of respect. If someone you respect as a level headed individual takes something the wrong way - or if multiple people do then you have to ask yourself why? Then it is only good form to apologize for the misunderstanding.
I don't know what criteria would label Askew as having done a good job in the preseason. He's a good with the ball but he is an awful blocker... Which is probably the reason why there are 2 FBs on the roster despite there being 4 HBs.
