The concern about turnovers and misplays is correctable with time and practice. As fans, the quality that the individual players have demonstrated is quite apparent. But also is the impression that the team has essentially a pickup-style game often found at the local YMCA. It is completely understandable with the newly acquired players and how their talents mesh being tested in-game with little to no practice.
In one view, the lack of practice may be a positive. Each player's raw talent is being shown in-game and under pressure. As a result, Coach Christie and assistants can fashion a custom game plan based on what is actually demonstrated on the floor. This, rather than the Brown tendency to try to fit players to the pre-determined scheme (aka: square peg in round hole), provides a wealth of player information and tendencies that can be built upon to maximize potential.
Once the indicated game plan is developed, it is then that organized practice can cause the team to bloom.
Coach Christie seems to recognize this outlook. This recent game where he "went big" with the centers is an example. Another is the resting of DeRosan that resulted the outburst he showed closing the game.
There are two games remaining before the break to further gather information and insight. After the All-Star game, a reasonable expectation is that the player parts will be refined, practiced, and in cohesive winning form that will carry the team to playoff success. Perhaps not all the way, but enough to open some eyes to the talent now in Beamtown.
