Easy guys.. easy!
I think its time for us fans to realize that BD actually has still got some massive technical deficiencies...and there are no short-cut ways around those weaknesses. Siddons has definitely done the good work of shaking off the subcontinental-style hype of emotions over solid developments. He has rightly identified the weaknesses of the players and has focused on curing those. He is a man of maths..and thus have chosen the path of not casting the spell of falls hopes.
If the team keeps progressing like this..I personally am more than happy with waiting another 5 years to become a real Tiger.. rather than an unpredictable Eid-style side.
Well...you only get one chance to make your first impression somewhere...!
