Just for reference, here are the 9 others.
10. Gilbert Melendez 13 fight streak
9. Chuck Liddell
8. Ben Askren
7. Jon Jones Current Streak
6. Rich Franklin 14 fight win streak
5. Matt Hughes
4. Cro Cop
3. Wanderlei Silva
2. Shinya Aoki
1. Fedor
This list really is full of shit for the reason that it compares today's standards of MMA vs the standards of 15-20 years ago. Also, it look at mma in other countries like Japan that has a different mma system and other organizations that just have lesser comp, can you really blame Askren for fighting who he did?? Furthermore, it look at fighters like Rich Franklin, Matt Hughes, Cro Cop at the beginning of their careers. Everyone pretty much fights lesser comp early on. Also, the only reason Jones is on there cause of one fight with Chael?? But aside from that it's been all top fighters.
The issue with Fedor when talking about his 27 fight win streak is that yes, it is padded in some fights. However, Fedor fought far more often than any fighters today, like I said, this is being compared to today's mma standards. Look at his fights per year...averages to 3 fights per year. Yes, from 2006 to 2009 his fights per year fell through, but that was because of not being signed to a consistent organization. From 07 to 09 he went from Bodog to Yarenoka to Affliction to SF. When is in one place, he's active.
