The other day a coworker and I were discussing the possibility of Blake signing with Boston in a few years. With the Big 3 retiring (or coming close, at least in Pierce's case), Blake could step in nearly seamlessly and run with Rondo for a decade.
What Blake provides is a hyperathletic package - albeit without a clear jump shot yet. What he needs is a pass-first point guard. In many respects, I see parallels between Blake and Malone: came into the league as a well-rounded player yet clearly needed improvements in several key areas. If Blake can continually build on his skills every summer (and I'm sure he will) then he will emerge as the premier power forward for the next 10-15 years. That's where Rondo steps in. Can't shoot worth a lick (evidenced by his defenders constantly giving him yards of room) yet is happy as a pig in mud to try his darndest to rack up ~15 assists. I won't go as far as to say Rondo/Blake could be the nouveau Stockton/Malone, but if I'm Danny Ainge, I will sell the farm to test the hypothesis.
