Basket interference, T or nothing?

[kycat1]

Had this play the other day. Need some advise.

A1 on a fast break, goes up for a dunk but loses the ball near the top of his dunking action above the height of the rim but outside the plane of the rim. He brings his hand forward anyway like he was going to dunk the ball and grasps the rim breifly enough to pull it down a few inches. When this happened the ball is slightly behind A1's hand but not in the plane of the rim. Then after A1 lets loose of the rim, the ball catches up to A1 and it goes through the basket.

Do you have BI thus no basket (but the ball was never in the plane nor on the rim while A1 was touching the rim), a T (for grasping the rim, so no basket)or nothing and count the goal?
