Picking/hiring people is a complex issue. There are myriad variables. The leadership team in place at OBD, it appears, recognizes that and did what they needed to do: fix culture first. That includes unloading malcontents, bloated contracts, etc. This could be a different thread unto itself.
Next is figuring out the mentality of the ‘right’ fit. I have no idea which ‘tools’ they use (Meyers-Briggs, DISC, ISPI, etc.) but, whatever it was, they understood who Josh was/is.
Another component is physical: that was a given.
Lastly is patience. This may be the most difficult, to be honest. Very few enter the league as who they will become. Once you lay your claim on someone as a draft pick, you really need to see it out and trust your coaches.
Given all of this, I suspect there will be countless other teams trying to replicate Josh but very few will due to them not grasping one of the components. Those will be, in order, culture, coaching and then patience.
