When does value start in the NFL Draft?

The notion of value in the NFL Draft is a funny one.

We discuss value as some idea based on where a player is rated by pundits before the draft and then where they are picked in the draft.

The thing is value is really defined as the overall impact a player has on the team and where he was drafted.

For instance, Justin Bethel was a great special teams pick by the Arizona Cardinals.

Drafted in the sixth round of the 2012 NFL Draft, Bethel had a great overall career as a special teams contributor for the Cardinals and now the New England Patriots.

He was a three time Pro Bowler for the Cardinals on special teams, but overall he was picked at the right spot and did more than enough in his time with the team.

However, his value was probably accurate, right?

So, how do you define value?

Was David Johnson value, or does the lack of longevity mean he wasn’t a value?

What about a John Brown, who has put together a nice career, but not for the Cardinals? Was he good value?

What are your thoughts on value in the draft and how to factor it?
