I don't think Bohley understands the concept of football. He probably thinks he is an owner of a NFL team with overtime and field goals etc.
My guess is that he wants somebody who is very positive but compliant...........you couldn't say Tuchel was either. I've worked with a few American bosses and they just don't get the European personalities at times. They do not like anything negative nor criticism of others except when it is "downwards" in the authority chain. Sometimes even the wording of a sentence riles them. For example I've had problems using the phrase "I'll do my best" which we use to mean "I'll do everything I can to make it happen"; they wanted me to say "it will happen". They like people who "accept responsibility" and who don't blame others.
Ok so this is all speculation and I have no idea why Tuchel was sacked........I don't believe that it was purely the results. I do think it was a clash of personalities.
Tuchel would be an awkward type to deal with and a bit spiky. I can't imagine him being uber positive. He would be a realist with a hint of negativity.
Who is ultra positive and would tell the owners what they want to hear? Only one man for the job.
