Still, a glitzy big play completion or a huge run up the middle will always be more fun to watch than a 3-yard loss or a pass deflection.
Or you could say "an 86-yard interception return for a touchdown is more fun to watch than a 3-yard run up the middle".
Yes, and a 90 yard hook-and-ladder is more fun to watch than an 86-yard pick return.
Which happens more often? A nice 8-yard run where the RB picks his way through traffic, or a huge sack or interception? The equivalent to a twelve yard completion is a pass deflection, or maybe just good coverage that forces the QB to throw the ball away. The former is more exhilirating than the latter, for me. My point was - a sweet long pass completion or a breakthrough first down run, are positive plays on offense. Their equivalent on defense, stuffing the ballcarrier for a loss rather than allow him to gain 4 yards.
Most plays in a game tend to go the offense's way. It's a matter of preference, of course, but it's how the game is nowadays. For me, I enjoy high-scoring barnburners more than games where both teams can't move the ball at all and not a lot of yardage is put up.
Even the best defenses don't always stop offenses, though. I know many people are high on defense now in the Bo Pelini era, but take last year, for example. We put the clamps down on many teams and still had to suffer through watching steady drives, yards grinded out on the ground, and the big play allowed here and there. Offenses in football are not supposed to be stopped. They are supposed to put up 200 yards on the field a game and call it a 'very bad day.'
It's not like I don't enjoy watching defense. The Arizona game, and the Big 12 championship with Texas for example, were just flat our ridiculous performances and an awesome sight to see. Very rare for defenses to put up games of that caliber though, so in general I do watch games for the offense. To each his own
