Im with those that think the system should be changed. The bigs are primarily shooting 3s. There is very little balance to this Offense. The team has begun to change as Crowder has started to put the ball on the floor and put pressure on teams slashing and taking one dribble attack pull ups.
I would love to see more diversification in this offense and maybe that comes with a more dynamic wing player but until then I guess we are stuck with good shooting bigs who struggle to rebound and wings that dont attack the basket consistently.
The system is winning us games but all I know is the Cavs won it with a player like Drummond and so have alot of other teams over the last 5 years.
I think that a key point in all of this is the difference between regular season basketball and playoff basketball. There are a lot of systems that can give you a win in a single game, facing a different opponent each game.
Once, however, you face the same team every game (and considering the fact that most teams in the playoffs are good defensive teams), things can get really interesting really fast. If a team relies, as Boston does, on the 3pt shot, there's a very good chance they won't be getting a lot of open looks—and converting those looks—4 out of 7 games (unless you have Steph Curry, which we don't).
Boston has shot well in many games this season, but we've all seen what happens when it
hasn't shot well from 3—they struggle, and it's because they're not a dynamic offensive team. They don't have multiple players who can put the ball on the floor and create shots, and they don't have a low-post threat (outside of Smart when he's matched up with smaller guards).
