At the recent youtube video posted by tdawgg (https://youtu.be/Or_8mRNdeEI?si=qlIToqSd5dqet44u watch the "Recap" part only if you want the minimal context), he talks about NRG's mistakes against MIBR and gives his speculations about why they kicked Verno while claimining to have some inside info.
From what I understood from that video is that there was a problem of accountability and people being responsible for mistakes during vod reviews and scrims and that caused the divide between FNS with 2 other players and Bonkar and Verno. Eventually it came to the point that org was forced to choose between FNS with 2 other players (probably ethan and som) and Bonkar and Verno and they decided to stick with FNS.
(Speculation)
So it seems like Verno was quiet during vod reviews whole time and when they lost at kickoff with the performance from FNS, he blamed FNS for the losses and didnt take responsibility on the losses and that caused the divide idk.
Whatever happened behind the scenes it will never come out openly anytime soon, this is all just speculation but NRG fcked themselves with mid-season roster move and coach change now they have to play catch up for the rest of the year.
