It's a slump, they're losing to bad teams as well as good. The record vs. good teams/bad teams is irrelevant.
Unless you're Milwaukee or the Lakers, you probably don't have a great record against teams with winning records. Toronto is basically 1 game behind us, they have a terrible record against teams with winning records, Miami is 1 game ahead of us, they have a better record against teams with winning records. Does Miami having more losses against Teams like Orlando make them better than us? Likewise, does Toronto having fewer losses against teams like Atlanta make them better than us? As the great Bill Parcells said, 'you are what your record says you are'.
We've proven we can beat good teams. We've beaten Milwaukee, Miami, Denver, and came within an eyelash and a few bad calls of beating LAC on their floor.
The comments in these threads are so myopic. "Big man" "shooter off the bench" etc. Would those things be nice? Certainly. But they're not going to matter when Jaylen Brown gets torched by Marcus Morris' brother, or Gordon Hayward goes 1-10, and really, nothing is going to matter when a team is shooting 60%+ against us.
We're losing because Jaylen Brown, Jayson Tatum, and Gordon Hayward (and in some cases, Marcus Smart) are not doing their jobs on either end of the court. Blaming it on anything else is just fantasy.
There's just too much pressure put on those guys.
All the NBA knows the Celts are just about wing players.
Contain the Celtic wing players and the Celtics lose.
I think it's very obvious that's what opposing teams are doing to the Celts right now.
The Celts are a one trick pony, no diversity on offense.
Relying solely on wing players and Kemba's 3-point shooting is not enough.
Celts don't need a big man?
I don't remember a decade where the Celts won a championship without a quality big man.
