When i came on board as a Liverpool fan, i was all in on the Rodgers hype, primarily because the fanbase had lost their minds. I turned on him after 3/4 of a season. I wasn't a big fan.
Klopp is a proven commodity. Won two bundesliga titles with BD, made it to finals of CL, and has turned Liverpool around from being kind of a joke, to a team legitimately competing for titles.
As for Klopp's ability to develop players, that's crystal clear on this team. Firmino, Origi, Lallana, Henderson, Lovren....those guys were going nowhere under Brendan. Klopp has turned them into really good players, plus he has a history of doing this.
Look, Pulisic is going to be fine at Borussia or at Liverpool. I just don't think it's all that risky for him to go work under Klopp, who all things considered is a better and more proven coach than Tuchel.
