In poker, bluffing is always a bad idea if you think the other players at the table have any idea what your hand is.
The Lakers, and pretty much the rest of the league, know exactly what the Celtics have. And to be honest, they shouldn't do anything to try to screw it up. The Lakers only want Ball because they CANT get Fultz at #2......unless of course, some ridiculous scenario happens, like the Celtics drafting Ball, in attempts to force the Lakers hand.
The only teams we should realistically be fielding offers from is Philly and Phoenix. Trading with them gives us a selection of Josh Jackson or Jason Taytum. I just don't see either team giving us one of the players we would actually want to make the trade down.
For trading with Philly, we should be asking for #3 and Simmons, but no way Philly does that. They offer us some combo of #3, Saric, Okafor, and future picks.....in that case I'd rather keep Fultz.
With Phoenix, we would be asking for #4, Chriss, and Booker for #1. Phoenix says it's too much, and I doubt Boston takes #4 and just one of either of those guys. As talented as Booker is and Chriss could be, Fultz still far and away has the All-NBA potential that I'm not seeing in the combo of players we walk away with in the trade.
