A friend of mine sent this to me weeks ago. Some article on the net.
Hurricanes (4 and 5 star player totals):
2006: 46
2007: 45
2008: 42
2009: 42
2010: 40
2011: 28
2012: 28
2013: 23

Having 40 or more 4 and 5 star players is of course not a guarantee for success. For example, the University of Texas has easily had over 40 four star players each year for a decade and has not produced much in the way of results while Miami did not go under the 40 player threshold until Shannon's reign. But having highly rated players certainly raises the odds of success.
For a quick further comparison of roster strength in during 2006 and 2013 (the lowest year), let's look at the number of 4 and 5 star players by position. And I'll throw in 2014 as well just for fun:
