"So what do we make of all this? In some cases, frankly, I was surprised to see the numbers as close as they were. No team is more committed to the draft than the Packers, and their roster hit rate in recent years hasn't been much better than the Lions'. The biggest distinction might be in depth: The Packers have 16 backup players that they have drafted, while the Lions have 10."
The number show Mayhew is not far off in his drafts from Ted Thompson who is more committed to building through the draft than anyone. In fact the point of the article is that Mayhew hasn't been as bad in his drafts as people think.
Maybe it's perspective. People who think Mayhew is a bad drafter see the negative in the article and people who think Mayhew has done alright see the positive. But from my perspective the article serves to show that while Mayhew hasn't hit on all cylinders, he's closer to being a good drafter than a bad one.
