I'm not horribly worried, to be honest.
Daniels is clearly not in NBA-game shape and it's showing on both ends. LeBron/Wade are eating him up with the help of the refs. On offense, he is either missing his type of shots or getting stuffed.
Pietrus would be a big upgrade, Pierce a giant one.
We are 1.5 games in. KG didn't fall off a cliff. Ray can still run and shoot. The bench is better. Pierce isn't missing the first half of the season. Rondo looks like the player we needed him to become.
The guys whining and complaining now will be the first one's changing their tune in April.
