The problem is the unknown variables. A top ten recruiting class simply means you have the physical talent to be a good football team. The mental aspect once a kid takes a leap from HS to college is the biggest unknown variable. How do they adapt? Do they struggle with classes, do they get homesick, do they let other distractions (girls, parties, etc.) take up time that should be devoted to football or the classroom? How many kids never live up to their rankings? Happens everywhere all the time. The academic side at ND makes that more difficult than most, so you have to get the highly ranked kids that fit the ND mold. While BK has had ranked classes, his first few years we saw where we lost some because they weren't a good fit for ND. Look at BK's classes recently and the makeup of the kids is considerably different IMO. I think BK had to learn that and he did.
Great post. I just wanted to add to the bolded:
2010: #14
2011: #10
2012: #20
2013: #3
2014: #11
2015: #11
Average: #11.5
Now consider that players still on the list of commits (on Rivals) include guys who either transferred due to one reason or the other, suffered career ending injury, or left early for the draft or other reason ("early" as in left eligibility on the table, even a 5th year). BTW, I'm sure I've missed some or have mislabeled some. Go easy on me...
2010: Danny Spond (4*), Matt James (4*), Cam Roberson (4*), Louis Nix (4*), Kendall Moore (4*), and a couple other 3* players
2011: Ishaq Williams (5*), Stephon Tuitt (5*), Aaron Lynch (4*), Eilar Hardy (4*), Troy Niklas (4*), Ben Councell (4*), Davaris Daniels (4*), Matt Hegarty (4*), GAIII (4*), Golson (3*), and a couple others
2012: Gunner Kiel (5*), Will Mahone (4*), Davonte Neal (4*), Tee Shepard (4*), Justin Ferguson (3*)
2013: Eddie Vanderdoes (5*), Greg Bryant (5*), Mike Heuerman (4*), Rashad Kinlaw (3*)
2014: Kolin Hill (3*), Johnnie Williams (3*)
2015: Bo Wallace (3*)
Note: I'm not even including the guys from the Weis era who left early. Guys like Clausen, Tate, Rudolph, Armando Allen, Shaq Evans, Wood (I think)...I'm sure there are plenty of others.
Again, I'm sure I've missed some but look at that attrition! I'm not saying that other schools don't experience this, but this is exactly why you cannot look at recruiting rankings and expect outcomes on the field to reflect said ranking. I'm sure if Rivals re-ranked the classes after seeing how many guys either didn't step foot on campus or who eventually transferred, it'd drastically drop that ranking. So while BK has "technically" averaged a #11.5 recruiting ranking (per Rivals), I bet with all the attrition that it's closer to #25 (or maybe even worse).
(You have no idea how gut wrenching it was to make that list. My God, what could have been...)
