Bad days will always happen on a team and might that time the momentum is not on their hands so its early to tell that Nicholson is not very much effective to his team since he just newly installed on the line up. Maybe on 2nd or in their third game if he still cannot provide what many people expect to him then we can say that Powell is perfect player between these selection.
I agree with you, the first game might not the best thing to base his greatness he just arrive and the chemistries among them is not that established yet, and the locals or his teammates didn't perform well so again it's not good to bring all the burden in his shoulders, the only thing here is the team will be meeting another caliber squad in their next game, Nicholson will be tested here and if in case another loss he might be judge and the management might activate Powell instead of him in their next following games..

I expect big changes in their performance on their next game, they'll be up against SMB which also a good team, SMB is probably as good as the SMB, so it will be another big challenge for him, also, I'm thinking maybe bookies will still make them as a favorite due to the "bounce back" thing, well, I hope they'll play more competitive basketball, or just remove Nicholson if we still see the same result on their previous game.
After that loss against Ginebra, maybe yes they will be getting a decent odd but the margin is not that far compared to how bookies gave them playing against the Gin kings, though it can be a good trap for bettors, we don't know what adjustments Bay Area will undergo after losing on their last game, we will expect another great game and hopefully just like how Ginebra give everything SMB will feel the pressure in protecting the pride of every Pinoy fans.
