Are our defensive players too small?

Upon a debate I came across on whether our defensive players were much smaller than "before".  I did a little research on one of the recruiting sites on what type of recruits we are getting now (under current coach) compared to 2002-2004 (under past coach). I was very encouraged with my results,

Remember these #'s reflect the defensive side of the ball (before transfers / position switches / etc.

Current Staff -  AVG weight (defensive line) 264.20 (3.8 stars)  / LB wt. 209 (3.67 stars) DB wt. 188.25 (3.38 stars)

Past staff - AVG weight (DL) 266.88 (3.75 stars) / LB wt. 230 (3.75 stars) DB wt 191.86(3.71 stars)

I guess in short, the reason for my optimism is, the past coach had these results in the middle of his "term" following years of Big 10 champs, a 3 year rcord of 28-10 and within 5 yrs following a National Championship. The other had to persuade these recruits after a coaching change in December, the biggest upset in college football history AND a combined record 16-20. I will say this, there seemed to be MORE defensive recruits under the past coach vs. the current-
