No, BR hasn't improved us. Lets not be biased now cos he's the current boss, but last season at this stage we had our first trophy in 6 years and only were 1 place behind where we currently are which as Carheex said doesn't really matter, lets not use our red tinted specs cos he's in charge, imo were worse off based on trophies alone.
Well, based on trophies alone, no one can argue with that, we won one under Kd and this season we haven't. However, I think we have to take into account what our future holds, and honestly, under BR I can see a future, I can see the team progressing and improving, whereas under KD i didn't quite have that feeling. Perhaps because KD also wasn't given enough time.
Once again though, this is just my opinion and as Carheex has pointed out basically, this is all based on opinion.
