I wouldn't take it as a compliment to the team if you take out the word boring.
He basically said "they're good, but they're not that good . . . they're not Lakers good" It's a slap in the face that he'd have the audacity to think, let alone say, his team matches up well with this team, which has been a juggernaut through 45 games.
If the Spurs had the same personnel they have and were playing the way they've played to this point, but they were the Lakers and not the Spurs, he wouldn't have said that. Conversely, if the Lakers had the same personnel they have and were playing the way they've played to this point, but they were the Spurs and not the Lakers, they would no longer be the favorites.
