Hmmm... Some friendly brotherly debate is required I see.
Nothing more than an effort to help you understand my position in this regard, & understand your position as well.
I never realized we were so far apart in our personal determinations of the Top 10 Rankings, I'll have to take a look at your Top 10 rankings again !
You know where you can find mine !
I never stated I was basing my decision on Welterweight fighters who finish fights
every single time, so I'm not quite sure how you interpreted that from my post or why it was raised as a means to rebutt my statement !?
My comment was addressing Matt Serra's inability to finish fights and no other fighter !
I'm not going to breakdown the the top 10s in this division with stats, as it would take up too much of my time... but since you mentioned Koscheck, Parisyan & Fitch above, I'll address those examples that you have chosen to compare to Matt Serra.
I have all of those fighters you mentioned placed above Serra for good reason in my personal Top 10 Rankings, that is until Serra can prove otherwise :
Josh Koscheck I have at 4th with a 10 - 2 record (83%) of which 60% are by finishing his opponents.
Karo Parisyan I have at 7th with an 18 - 5 record (78%) of which 50% are by finishing his opponents.
Jon Fitch I have at 3rd with a 17 - 2 record (89%) of which 59% are by finishing his opponents.
Matt Serra is not in my Top 10 with a 9 - 4 record (69%) of which 56% are by finishing his opponents, and IMO a lucky fluke win over GSP.
The examples that you have chosen I have placed above Serra either due to the fact that they have more experience, a better winning percentage, a better finishing percentage, or a combination of all of these reasons.
To make it bit easier to see my point I compiled this mini-spreadsheet :
