I have a DRAFTKINGS - NBA Fantasy ?? - PLEASE HELP ME!

Hi guys and gals - 

Please help me understand something.....in DraftKings NBA Daily Fantasy.

I have watched several "screen names" that are labeled as "Pros" or guys who have played and won significant money doing Daily NBA Fantasy Contests with multiple players or in the HeadsUp (one on One) entries.

What I have clearly noticed is that almost All of the "PROS" in a head up contest have the SAME EXACT LINEUP in the NBA !!?!?!?

Here's the question that is DRIVING ME INSANE......WHERE ARE THEY GETTING THESE "COMPUTER GENERATED" Line-ups from??

You can tell they are coming from the same place cause they're all THE SAME!! 

What Site / Software / Algorithms / Company are these guys using to get these SAME NBA Lineups....

They are VERY HARD TO BEAT ......I beat some guy last night by about 1.5 points.....So, BARELY !

Often they ALWAYS WIN against the average Joe Schmoe....

Any help - Any CLues? Any facts to share with me? 

Please feel free to share with me where these so called "PROS" are getting their Lineups from? 

what did you come up with this question i been   asking for yrs
