I dont think the crazy flips are lack of drive. Pro's know (or should know by now) that you lose all your power when you leave your feet, and leaving your feet is what causes the helicopter tackles. I recall Sage Rosenfels did it this year (QB...what does he know about running), and lost the game cause of it. Also John Elway did it to dazzling effect in Super Bowl 32 (i think it was that game anyway).
I think what you're seeing is more evenly matched events, which takes away the individual effort that you seem to yearn for. Except perhaps for NBA games, which are more individual than College B-ball.
