Bump coverage from an offensive coordinator veiw?

Against a pass heavy team, I love to run press coverage on the receivers on the LOS. It's not as good, IMO, against a WR in a flanker alignment because he has room to throw some moves on the DB. I think one of the greatest advantages of the bump is it throws off the timing of the short game. Also, I love making a receiver take two or three steps on the LOS instead of downfield at the start of his route.

I feel the major disadvantages of press coverage are 1) you have no secondary force/contain player against the run because your corner is completely focused on the WR, 2) the fade stop route is completely impossible to defend unless your corner is not able to run with the receiver on the fade, in which case he happens to be able to play the route because of his ineptitude or lack of speed 3) WRs that excel in getting off the jam are open immediately (and as a WR coach, we practice this every day using karate blocking techniques to pin the arm and shoulders of the DB and get him on our backs right now!)

I like to use the technique against Bunch or stacked formations because often the pattern development depends on the frontmost receiver getting out and rubbing a defender or clearing a zone, so the longer we can bottle up the pattern development, the longer our D Line has to get to the QB.
