Interview 15 coaches...
Aske every one of them: "If we were to hire you name three front office men you'd like to work with as a GM?"
If you see a name that pops up a bunch then you've learned that's a GM candidate who is well respected and maybe you should seriously consider that guy.
This is just one of many reasons to talk to lots of guys. Maybe someone blows you away in the interview you hadn't really considered before. Regardless, there is nothing wrong whatsoever with taking your time and talking to lots of people.
I see your point. *BUT* Bulls just finished getting a draft pick taken from them for tampering with Billy. All those college football coaching changes just happened without a single interview. Cubs hired Maddon and got investigated without a single interview.
Why? Because they knew exactly what they wanted, put out feelers and hired their Plan A. But all that happens when you have people running things that know what they're doing. Cubs with Theo and Bulls now with Art.
Bears brass has ZERO clue what they're doing and that isn't even up for debate. So my apologies if I see things differently than believing they're going to get blown away from an interview like if this is a manager for a Walmart.
