Yeah I guess it is more of a strategy or approach to recruiting rather than a limitation.
I always look at it like if one year I can get the #1 Qb (like ND w/ Claussen) and the next season I can get a top 3 like Christ, then fair play to me. But I don't see many schools getting QB's of that quality in one season. Also if after getting Claussen I can only sign some 3 stars for a year or two and then bring in a top 5 guy it creates a position battle.
My dynasties are usually Maryland, and sometimes a second with FAU. So its not like I am automatically going to have all the 5 * guys interested right away.
