Had the same thing last Thursday. I blew whistle, went up to Trail and said "I had his foot on the line" he's "You're sure?" "Yep!" I try to get it done quick!
I don't know what I would do if it is a 1-point swing that makes a big dif in the winding seconds (6....5...4...) Should we put time back on, let players get a chance to get coached, IMO we whistle as quick as possible (you should know when you see the shot up and you have a descrepency with your partner, that you should kill it as soon as you notice it goes in {not watching ball though

}) It should take 5 seconds and flow of a closing game shouldn't be interupted that badly.
Also wondered if anyone has changed a 2 to a 3. I don't see it happening but if T has a foot on the line in a gray area of coverage and I see wood b/t shoes and line, we got a situation.
Thanks All, this forum has been very informative!
