I assume that those who hired him took into account that this is his first job as manager.
And they gave him more leeway.
We should ask our American colleagues here how KSE choose managers for their American clubs, Nuggets and Rams?
Is it normal for them to choose novice?
I never followed American football and I have stopped following basketball about 25 years ago, so I don't know.
Sean McVay was an assistant with the Washington Football team who was seen as a genius, wunderkind of offense at a young age. From his time as a QB coach to eventually calling plays. He came from a football family. He was seen as the 'next one' to get. Deemed a prodigy. And they got him. It was his first head coaching job. He inherited a team with some talented players they drafted well from previous years, but the QB was considered a bust. He fixed Goff. Stacked all their chips and traded draft picks to win a Super Bowl in their 2nd appearance under McVay.
Malone for the Nuggets wasn't a big name, but his dad was an NBA coach. Career assistant and failed at his first head coaching stint with Sacramento. Nuggets were his 2nd head coaching gig. But he and the Nuggets steadily kept improving year after year continuing to draft well. They did it the ole fashion way. Not a lot of fanfare. Just making sound decisions in hiring a coach, drafting and acquiring and developing players. They ultimately won the championship.
Two distinct cases in the hires.
