When your WRs are blanketed and Ed Reed is picking off everything in the middle, you tend not to put the ball in the air a lot.
Miami was only tied for 17th in the country in yards per rush allowed.  That's not elite.  VT, in a close game, threw as many completions as INTs.  Buchanan, Reed, and Rumph were all first rounders, and a backup CB, Rolle, was too.  
One thing I've learned, by studying all the good teams from the past 40 years for the game I made, is that it's VERY difficult to be super-elite at both run and pass D.  Not one team allowed 2 or fewer yards per rush AND 4.5 yards per pass.  
I think generically, most defenses try to key on the run to make teams one-dimensional.  I guess 01 Miami went the other way on that.
