No doubt Indians are very good in their home ground and especially against Bangladesh but do not underestimate the level of Bangladesh cricket as they win the 2-match test series from Pakistan in Pakistan and clinched victory from Pakistan.
Do not overestimate Bangladesh just because they won a series against Pakistan on their turf. Pakistan are going through a horrendous phase which is primarily why they lost so comprehensively. Think!
I think the reason for this was the supernatural force of BCB on the Bangladesh cricket team. Due to which the players could not play freely.
Supernatural force? This made me chuckle. Does BCB possess some sort of magical powers or something? Unique reasoning.
