T.J. Watt’s interception not only was a play of the year candidate, it completely swung the momentum to Wisconsin’s favor.
With UW going ahead 7-3 and Purdue’s first offensive play after the go-ahead score, Watt effectively ensured the running back heading toward the flat was accounted for, then climbed up the ladder to pressure Purdue quarterback David Blough on a bootleg.

Catching his own deflection of Blough’s pass, it was simply a matter of outrunning the signal caller to extend Wisconsin’s lead.
That ball security, though.
