BI or T

Really? Looks like I missed yet another one
A5 just jumped up and grabbed the rim for some odd reason (YMCA HS league). The ball was clearly going through! Hadn't seen that one before.

I went with BI and a player (who claims to have had "reffed") asked in passing "shouldn't that be a T"?
I went with selective hearing & didn't respond (live ball - I had a job to do)
Guess I'll have to man up & let him know he was absolutely correct
