The window for Kaepernick to complete a pass to a WR is smaller than any other QB's window in the NFL. He constantly has to fit a ball in to a wide receiver who is blanketed by coverage. The reason is that 49er WRs are the slowest in the entire league on average and Stevie Johnson probably makes them even slower. Now they hardly even have roster space for anybody who can stretch the field. What does the GM have against speed? Speed at wideout makes safeties play a few yards further back and opens up routes and running lanes. Their passing offense was 30th last year. This is still a passing league and their current philosophy isn't working. If they had even an average passing game -- they might be on "Quest for Nine" instead of finished second in their own division.
