Source Material: Original Post, Definitions, 2002 Class.
I think the McBean Rating discussion compels me to stop for a moment and tackle a couple problems.
Before that, I wanted to give a summary of the informal voting that took place in the last thread as it related to the 2002 class (note: it would be helpful if more readers would vote – the number of votes was small, although the justifications were scholarly). Here was the 2002 class career ratings proposed after the McBean Rating definitions were debated:
The following votes were then cast:
Five-Star: Two votes
Four-Star: Three votes
Three-Star: Three votes
Two-Star: Zero votes
Three-Star: Two votes
Two-Star: One vote
Single votes for Bihl as a four-star, Breaston as a four, Tabb as a three and Riley as a three.
All votes are not equal as arguments of varying persuasiveness were offered. In the debate, wolfman81 almost perfectly captured what still remains a point of contention: how to use the NFL draft in our assessment -
Notice that in all of these cases, I consider the college career first. If there is some doubt about what category the player should fit into, only then do I consider the NFL draft. The NFL draft is a tiebreaker, but only when there is a tie to be broken. In my mind, 1st team All-American = 5-star McBean. All-Conference = 4-star McBean. Starter = 3-star McBean. There can be exceptions to this rule (Tom Brady was not All-Conference, but I think he should be 4 star due to his leadership on the field and other intangibles. As he was drafted, the NFL assessment backs this opinion up. The fact that he will likely be a first ballot NFL hall of famer cannot bump him up to the 5-star discussion; at the same time, it does not harm my 4-star rating.) But, I think that this rule sets a minimum standard.
The new 2002 McBean Ratings are as follows with only one change – Harris drops to a four-star. Mark Bihl was pushed hard as a four-star, but his career falls short of making a significant impact, just as Harris clearly falls short of an elite career.
The conclusion one would then draw from this data is that the 2002 class dramatically underperformed. To give you an idea, this would represent a drop in the team rankings (if the rankings were based upon average stars) from 10th to 21st, using an average of the 2002 through 2009 data.
Now, the problems:
- How do we handle the math for players like Dann O’Neill, Quinton McCoy and Taylor Hill? Players who never saw the field and did not stay. My original method counts these players in the Rivals list, but does not count them at all in the McBean list. For example with the 2002 class above, the 21 players in the Rivals list are all counted and the denominator is 21. For the McBean review of their careers, McCoy and Berishaj didn’t have a career at Michigan, so they are not counted and the denominator to determine the average star rating is 19. If we eliminate the two players from the Rivals list, do we fail to take into account the reference point of our evaluation: the quality of the entire incoming class as judged by a recruiting service? Yet, by taking them out of the McBean career list, do we fail to punish the staff for recruiting players who could generally be considered a bust? However, if we rate them a zero or even a two, we ensure that pretty much every class will underperform badly (counting both as a zero, the McBean average would drop to 2.81!). I am both befuddled and in need of a paragraph break.
- Second, the ease with which we rate invisible players as two stars devastates our average rating. We rarely recruit two-star players, yet because every team logically has many anonymous backups (seventeen preliminary McBean two-stars over the first five classes I’ve looked at), we have exceeded a ratings Chandrasekhar Limit and pulling each class down into a black hole of underperformance. Case in point, I offer the 2003 class which, if this class doesn’t qualify as a recruiting success and overperformer, then none will:
EDIT, August 29th, 9:24am: Gentlemen, after reading below and thinking about the problems presented, I feel we made a mistake with the definitions. Any viable Michigan players - this includes backups who do not see the field - should be get three stars. We could use this yardstick: any player who makes the two-deep during his career gets a third star. Also, we should be more generous with four stars for good starters like Bihl and Kraus.
Here's my reason: we must remain connected to our baseline system, Rivals. It is our point of comparison. Without a close connection, we can make no claims about under and overperformance. We recruit many three-stars, and while individually each kid hopes to be the next Pat White, the 30,000 foot reality is that those three-stars, en masse, are destined to be the backups. They are not underperforming, they are performing as expected.
This pushes some - not many and not enough to unbalance the finite four-star numbers - up a notch, because Mark Bihl and Adam Kraus cannot coexist with a three-star backup.
So, I am thinking we need to predominantly loosen our three-star standards to allow us to recognize backups as meeting expectations.
