If they're happy letting Rondo go, that's a very big mistake, Unless Schroeder can mesh perfectly and repeat his awesome year.
I think this may be a case of being greedy and overconfident...where they don't realize the effect Rondo had on that team...the greedy part being just looking at Schroeder's stats and saying wow we can be even better...without considering chemistry. Maybe that team has found itself, but prior to Rondo coming back they looked a bit lost. I'm not a good judge of Schroeder's PG skills (in the getting everyone involved, leading the team, taking pressure of Lebron sense), so willing to be wrong.
