No it wasn't. Bootle's should have been automatically flagged as he never turned to look for the ball. The CU DB was looking for the ball and in position to make the play, he just also happened to be holding onto our guy (who was also holding on to him).
Agree with Landlord. In real time, the initial one with the INT looked worse. But the textbook would probably say Bootles as he didn’t even make an attempt to see the ball.
