His coaching style still have that big impact for the team, but the players that he managing I think that's the big difference compared from those players that he handled from the past. I personally can say that they still don't have that caliber to be a championship competitor not unless the import that they are bringing is someone who can elevate everyone. That might bring the big impact to ROS, too early for concluding, it's the first game and everything can happen maybe better to bet during the live game to see it first the performances of each teams.
Coach Yeng is a relevant coach and his coaching style still give a huge impact to their team since many players still get motivated to play more better basketball because they don't want to get scolded by their coach. But the problem their is they can't get more better player since sister companies are always manipulating the league by taking those strong rosters that's why for them its really hard to get better players since they can't take any action to those big companies which manipulate the league. Maybe your right and this season their only hope is to get a impressive import that can help their team in various aspect so that they can possibly win a championship this season. But I really doubt it will happen since they would provably struggle since SMB and MVP group has so many stars on their team.
That's the point that I really wanted to brought out, there's manipulation and we can't deny that fact and if I remember it right coach Yeng is very vocal with how the league is being handled, in terms of being a contender, the chance for ROS is very slim just like what you mentioned the rotations of players, both SMC and MVP squads do have multiple stars who can help to carry the team compared with what ROS got right now.
