In college football this does happen, but its pretty rare. It happens mostly only when DBs are completely beat and have no deep help. But most times if the DB is close enough to tackle, hes close enough to attempt to break up the pass.
Like KG said, i rather see this than undeserved 50 yard bombs.
Also, the NFL DB's are sometimes so scared to get flagged that they barely defend the pass and allow easy catches. This change in penalty would allow defenders more confidence in defending passes.
Almost every new rule has been created to favor the offense, its time defense gets one break their way.
I agree completely. There's a big problem in that the refs are looking for any little contact to call a penalty on a defender on a long pass. They're already at a disadvantage in coverage, so giving the offense free yards on deep balls for what was incidental contact is pretty crazy. It's a big problem that is leading to the NFL's dominant passing offenses. It used to be that going deep was a big risk, because it had a higher chance of incompletion and a relatively high chance of interception. Now teams take shots left and right because they have an equally good chance of completing it as they do of getting a flag from the refs as soon as the ball lands incomplete (another big problem, waiting until it's incomplete to call a foul occurring before the ball arrived.) I'd be interested to see the rates on deep blls (30+) over the last 15 years. I'd be willing to bet the flag rates have sky-rocketed. Having a 15-yard penalty helps a lot, but they need to quit calling ticky-tack contact to help offenses more than anything. It seems like the NFL has conditioned refs to look for something to give the offense yards.
