This is big. If you're mediocre in high school and don't immediately show a lot of potential in college, you won't get much attention from your coach or your teammates at most DI schools. As a result, it will be easier to not train as hard, get discouraged, or burnt out from trying to train with the recruits who are a lot more talented than you. That often leads to guys not staying on the team, or just not developing in the way they could (even guys who were studs in high school but struggle early on).
If you're at a DIII school as a 9:30-9:40 guy, you, your coach and your teammates immediately see the potential for you to become a real leader on the team and to run at the national level. The expectations and beliefs of those around you do a lot to keep you motivated and create an environment where you are much more likely to stay with it and thrive.
Every now and then you'll see a 9:30 guy go to a D1 program and develop into a sub 14 guy, helped by the fact that expectations are raised and that he's trying to hang on to guys that are at a really high level. But i think that's the exception much more than the rule, and more often kids will burn out or just not enjoy it that much because the coach and team aren't that invested in them.
That's the real reason DIII is going to develop your average 4:20+/9:20+ guy better than DI, not the coaching. There are great coaches and shitty coaches in DI and DIII alike, its more about how you as a runner are going to fit into the training environment at a given school based on your ability level and to some extent (though less than people tend to think I'd say) your personality.
