Video Request: Illegal Screen or Block?

[crosscountry55]

Purdue @ Pitt, 12/1/15, ESPN2. Start sequence at 1:41 second half.

W0 dribbles ball into frontcourt right side. B21 moves toward W0 and contact occurs while W0 still has the ball (W0 was either looking to make a spin move or pass the ball....hard to tell).

T calls illegal screen on W0. I think most folks thought it was a blocking foul because of the way B21 moved up to attack the basketball, but I can also see the argument that W0 may have been screening (illegally) while in player control. Needless to say, HC of W was incredulous.

Unusual call. I'm looking forward to the discussion that follows.
