According to the "Trade Chart" which is used by NFL teams:

The first overall pick is worth 3000 points.

When you total the picks in the Watson and Wilson trades. They are very close to 3100 points.

So in the end what we gave up in picks to get Watson was basically equivalent to the first pick in the draft.

I would make that trade seven days a week to get a 26 year old Watson.
