What does any of this have to do with taking it personal? Really, the comments that are made have nothing to do with who takes is personal or not. The comments are inappropriate in my opinion. They are out of line. If a coach makes a comment about my partner, that is not acceptable. I am not going to let a coach "call out my partner" and just let that go. We are a team, I would want them to do the same for me, I know many officials that would do the same in return. It is no different when a player starts complaining. It will be addressed so I do not have to do it with the game on the line in the 4th quarter or late in the Second half. My efforts is to make the game go smoothly, not have any Ts or ejections because the coach started down a road I could have easily stopped.
Coach, you want to make this into a personal issue. This is within my professional bounds. I have ever right as an official to address issues that are deamed "unsportsmanlike." Now that is where judgment comes in, but it is my right to handle it. I just choose to address it by talking directly to the coach, instead of just pulling the trigger and ejecting the coach. Look at it how you choose to, but but they better know who they are dealing with. Because an ejection might just happen.
Peace
