Close from the lead on routine foul?

[Tee]

I'm getting some feedback regarding closing on a routine foul from the lead.

I understand that there is times when it is absolutly nessesery to penetrate the baseline, but what the observers are saying is that is is not desirable to close on most fouls. That the lead is close enough already. And that it is confrontational to close and birddog every time.

I see some guys who do a sort of circle close on every call.

Please give me your opinion on closing. What are the pros/cons?

I am mainly talking about the lead, but I am open to talking about the trail position. It seems obvious to me that the trail needs to close more aggressivly most times- true?

I almost exclusivity do 2 whistle. Any big differences re closing with 3?
