Dee Milliner Combine Primary Receiver challenge

Anybody know how to beat the zone? Just played seven times in a row and threw 21 straight interceptions. Not a single completion (or incompletion, for that matter). The second I snapped the ball there were no less than three defenders immediately blanketing the primary receiver. 99OVR Elway to 99OVR Jerry Rice. 21 int's.

How do you beat this?
