On offense, offensive line/pass blocking and on defense, defensive secondary/pass coverage. These are the areas that needed the greatest improvement.
After that it would be to see whether the WRs are running precise timing patterns/cuts and getting wide open. That was another area of concern last year. Finally, to see if the running backs are able to be great receivers as required in the WCO. The great 49er receivers would say that if one can get hands on the ball, he should have caught it. Gore, Dixon and the fullback must demonstrate great hands and ability to lock in overthrown or underthrown balls within their arm length and leaping radius. There have been instances where a slightly misplaced ball, was tipped and should have been caught by the running back, but instead became an interception. The running backs must make it a point to perfect this craft and do everything they can to get that ball or at the very least knock it down to prevent an interception.
