I'll look at both sides of this. For Brennan Othmann, playing for Wilson was probably (whether he realized it at the time or not) legitimately the best thing for his career going forward. Othmann had the proven offensive numbers, the world juniors pedigree, he was already drafted. Getting into a more structured, defensive system and learning how to win was exactly what he needed and will serve his future career prospects very well. He did come back and spent more time here than anyone else at training camp when it was super clear he wasn't coming back.
I don't know what to think with regard to what Owen Beck should want for the rest of the season. On one hand, his meal ticket in the NHL is going to be an exceptional two way forward, he's probably a third line centre long term but can be that on a Stanley Cup contender IMO. Wilson might be pretty close to the best coach in the OHL to develop that game.
On the other hand, if Montreal (or Beck) wants more offense out of him, he can go to literally all 19 teams in the league and be put in a better offensive position than he is with the Petes (playing with Purdeller and Lefebvre and inexplicably on PP2).
You see it in this thread, people not paying any attention suggesting he's worth less than trade deadline studs of years past because "the numbers aren't there". It's utter nonsense. But maybe he should go somewhere and light the league up for four months just to show he can (HINT: We all know he can).
Or maybe he'll just get Tucker Robertson dropped on his wing, stick around a while, and lead the Petes to the conference final to the dismay of ... Everyone on this message board.
