An equally valid theory: the Celtics are now being built AROUND Rondo, and they hired a young, smart coach to design the system which maximizes him instead of bringing an established guy into the organization. I don't see Steven bringing the Butler system to the NBA - he's gonna hit the analytics, understand the strengths of guys like Rondo, Bradley, Sullinger and Green, and design a brand new style of Celtics basketball. Rondo gets the chance to play in an offense designed *for* him, and we seek out the kind of high IQ guys who can handle a complex defensive scheme. Gotta think it would be fun designing the D around Rondo, Bradley, Green and Sully. All intelligent players and the former 3 have elite tools for the job.
Exciting times - I'm sure it'll get old at times while we're losing, but the future is worth being optimistic about.
