I hate Zone Defense!!

Pressure is the key regardless. That's why pass rushers make the 2nd most money behind QBs.

If you're playing man all the QB has to do is find the most favorable matchup... and the receiver doesn't even need to be open, look at all of those backshoulder fades that QBs throw, those routes only work vs man, also slant routes, if the WR beats the db off the line, he's done. Man defense also creates more running lanes for running QBs.
