Being intelligent and being wise are two different things.
Need to be intelligent to be a cap expert and deal with numbers.
Need to be wise when dealing with people. Marty is a smart guy, but he wasn't wise managing the team.
I know people who are intelligent, wise, great with numbers and good with people who I wouldn't put in charge of picking a grade school flag football team.
Some people are very well able to make numbers add up on a spreadsheet. But it's not enough.
Some people are good at scouting talent. But that alone also isn't enough to make a good GM either.
You have to be able to put the two together and recognize the value of a player in the current market.
The best way to prove you can do that is by working your way through the ranks from scout up to player personnel. Marty Hurney never did that. Dave Gettleman did.
Over the next several seasons, I hope we see a clear difference.
