Top 15 is already a hyperbole... 10 is simply an assessment I have to disagree with both in reality and fantasy basketball.
Steph, Russ, Lillard, Paul, Lowry, Wall, IT2, Kemba, Kyrie, Conley, Bledsoe, Dragic.... you can add another 3+ names to this list and I still probably wouldn't land on Dennis. Additionally, this is eliminating de facto PGs by non-positions, like Harden, Greek, Lebron, etc... you get the picture. Are you saying that you'd take DC over any of those guys in a heart beat...? A decision like that could cost you a championship in a fantasy league, and probably set back a franchise a decade+ (10-15 years) in real life.
In no metric can he be considered a top ten .. of anything really. I guess his average salary is top 10 (4/70)? Just genuinely curious to see how this assessment was made.
