Big b and his family always maintained not so cool vibes with him. maybe they do not take to jokes made by SRK in filfare awards shows. He takes centre stage and upstages all , with his with , energy and PR works , so much so that the towering AB also is overshadowed by the minnow SRK. may be this along with rivalry with bachchan bahu had to do something with the first family not tweeting or congratulationg SRK.
SRK is a man of brains and not a man of heart. If SK had a team and if his team ( read as salman khan ) had won , barring AB family again , everyone would have rushed to congratulate as he is a man of heart

Bollywood is all about films and less of cricket.
Besides, the many of the losing teams are owned by business houses, where the other film stars may be involved in brand-endorsements.
So, they play it safe by being on the overseas shooting spree...!
