I'm definitely not an advocate of drastic measures late in the season, but this has just hit an absolute new low. Blake has zero confidence at this point. The supposed "solid" description is simply not true anymore. He makes mistakes (and a lot of them). Even worse, his mistakes consistently lead to break away dunks by the opponent. They aren't your standard throw the ball out of bounds- miss a 3 type. They are throwing the ball away at halfcourt, blowing open layups, turning the ball over in transition (which always leads to a break the other way), and the worst of all is giving guys like Pryzbilla the ball at the three point line (with no hope of succeeding).
Now, Sergio and Bayless have essentially played like High Schoolers the last two weeks, so I'm not advocating starting them. It's time to start Roy with Rudy. This way, Blake can come off the bench hopefully this will alleviate some of the pressure on him. An added benefit is that this might help Roy establish himself early, rather than waiting until the second half.
The biggest thing here, is that at this rate this team is pretty much locked into that 7th/8th spot. If the move doesn't work, so what? Were we going to get to the finals with Blake? But what if it does work? What if they play well? Doesn't it completely change the off-season and what moves you make? The simple fact is that we know the outcome of Steve Blake "starting point guard". Let's gather some new information before it's too late.
