Mike Glennon-"Play actin Pass"

I cannot recall Mike Glennon executing the “play action pass” used so effectively by many of the top NFL QB. Even Peyton Manning who is a master at the play action  refreshes annually with Steve DeBerg. For those of us who watched DeBerg as a Buc QB we sat there for 3 or 4 seconds wondering who’s got the ball. Glennon should try it maybe more receivers could get open.
