Every time from the time salman came in JDJ, he got the best or at least the best from the rest celebrities.
The first time he got Yana who is a really good dancer
Then it was isha who is a professional dancer
And now it's DD who might not be as proficient In dancing as yana or isha but she covers it in being the colors girl and having biased judges and crazy fans who worship her
So my point is why salman always gets the better celebrity and have an added advantage right from the starting? Why not give him a less popular or less talented celebrity, someone like meghna malik, aarti or ekta so that he gets a chance to show his actual calibre of training a complete non-dancer.
Yes, he hasn't won the title yet but he still gets an added edge over other choroegraphers.
I'm sure being Remo's fav student works in his favour a lot!
