Bo literally said "we need more maturity" and then said "not that we were immature" - which seems pretty contradictory. Maturity could also simply mean they need more experience playing when we are expected to win, or we need to play more playoff games (which seems accurate, as he references the teams young players). Yes he did suggest they need more professionalism, but he didn't cite who needs that - maybe he's talking about himself, or several other young players on the team. He literally notes that he doesn't know if that was a factor in moving Teo and Gurriel.
Those who have been suggesting that obviously want to take Bo's 5 sentences and claim the W.
Is there potential that professionalism and changing the clubhouse culture were at play in those trades? Of course there is. But I have no idea if it was 90% factor, or 5% factor. Nobody does.
