Trail Blazers practice ended on Wednesday and a single player remained on the floor, shooting late. Same guy who always stays late.

It was Andre Miller.

The 11-year NBA veteran worked on his perimeter shot, and his young son, Dwayne, shagged rebounds. The pair shot, and shagged, until everyone else had left the court, conducted post-practice interviews, and headed off.

I couldn't help but watch. At one point, the kid watched as his father dribbled left, pulled up and shot. He repeated this pattern several times. So Dwayne gathered an imaginary ball in his hands, mimicked the dribble left, and pulled up himself.

The professionalism. The passion. The dedication to getting every detail right, even as few cared to watch. All of that struck me as not only what Miller has, but exactly what the Blazers need to get as a team right now.

The victory over Dallas was sweet. The play of three-time All-Star Brandon Roy, encouraging. But unless Portland gives Cleveland a crisp back-alley whipping tonight at the Rose Garden, none of this is going to be good enough.

Coach Nate McMillan said it himself on Wednesday as Miller and son shot across the gymnasium. Said McMillan: "We can't have slippage with our play. We have to execute, and set good screens, and battle through fatigue. We have to be consistent. We have to be locked in. We have to..."

I cut him off.

And offered, "Kick the crud out of Cleveland?"

McMillan smiled.

"Yeah, exactly."

We've arrived at the Leave-No-Doubt portion of the Blazers season. We've celebrated Portland's refusal to quit amid injuries. We've lauded McMillan's skill in getting his team to compete. And while there have been big games, we've been traumatized by this unit's inability to close out winnable games.

Victories over the Heat, Bulls, Spurs and Magic have made you think anything is possible. Losses to Sacramento, Indiana and Charlotte have made you wonder if pulling for the Blazers is worth the emotional investment.
