The first thing to understand about Aaron Donald's training camp holdout is that Donald is right. He is grossly underpaid relative to his production, and the victim of a system designed to limit both the income and the freedom of first-round picks in their first five years in the NFL.
The question, though, as Donald sits out the start of Los Angeles Rams camp, is this: What's his hurry?
Donald is a unique, possibly transcendent player. He has 28 sacks in his three years in the NFL. Only nine players in the league have more sacks in the past three years, and all of them are edge rushers (as are the next eight guys on the list after Donald).
