  1. I think the Packers just like to pre-negotiate all these trade up deals before the draft starts, whether or not they have some intense desire to trade up or not. We've heard this story every year under Gute.
  2. If you're going to mine the data set for patterns, you need to set aside a substantial amount of data to act as a cross validation sample. A priori we should know that the NFL draft data set is not rich enough to support this kind of analysis. The other possibility is to create a hypothesis before looking at the data, and then you can test your hypothesis (model) against the data. If you peek at the data beforehand, or let what you know about the data bias your hypothesis, then it doesn't really work. This kind of analysis works when you're using it to inform your own decisions under uncertainty, when you have skin in the game. Otherwise there is a principle agent problem - in academic psychology this is called the replication crisis.
  3. You shouldn't say your model has a "track record" or "results" unless you have predicted out of sample data.
  4. Ball is good at making decisions under constraints Gutenkunst is good at press conferences. Wolf's dad is cool Does not seem like a difficult decision to me.
