LS Mike Windt used a tennis ball to simulate snaps during a walk-thru practice Tuesday. During the 20-minute drill, Rich Bisaccia, assistant head coach -- ST coordinator, worked on proper formations and assignments for punts. The small ball made it more difficult for the line to see and properly react to Windt’s snaps. If anyone failed to execute his job to perfection, Bisaccia blew a whistle and the play was run again.
