The Blues have been careful not to brand 2013 a development season, even though it has been. If they had been so inclined, they could now make the claim that it no longer is: Friday's win against the Stormers was a breakthrough victory - the sort that said they are learned rather than learners.
The reason no one likes the term 'development season' is that it implies forgiveness for continued failings. Repeat mistakes are tolerated, accepted as the inevitable consequence of fielding young players who lack experience.
Of all the improvements the Blues have made in the past 12 months, the one that stands out is their relative consistency - at least in quality of performance, if not results. Unlike previous years, the Blues of 2013 have not blundered along seemingly oblivious to what happened from one week to the next. They identify problems and patterns and adapt.
Having been beaten up earlier in the year by the Bulls - a game in which they were guilty of trying to play too much rugby, they were patient and conservative in defeating the Stormers 18-17.
The Stormers, much like the Bulls, use their enormous pack to slow the game, to keep possession and frustrate teams. They use their driving maul and swarming defence to build the pressure and effectively goad more expansive teams into taking risks. When the Blues encountered their first African side - the Bulls - in week three, they were naive, error-ridden and rushed. Friday night's clash was their second against African opposition and the tactical approach and outcome were entirely different.
