IMO Jayasuriya would come in the top 5 ODI spinners in the least 10 years, easily.
Not a chance.
Last Ten Years Spinners
Murali 341 W @ 21.11 econ 3.72
Vettori 204 W @ 31.64 econ 4.13
Harby 184 W @ 33.42 econ 4.17
Sanath 177 W @ 37.73 econ 4.65
Hogg 153 W @ 25.94 econ 4.52
Gayle 146 W @ 31.99 econ 4.65
Kumble 146 W @ 36.25 econ 4.55
Warne 143 W @ 26.83 econ 4.38
Salqain 133 W @ 24.89 econ 4.28
Sanath is 4th on the wicket taking list despite playing 41 more matches than the next player (Murali) and 60 more than the next (Vettori). Only two names on that list have played more matches in that time than have taken wickets, Gayle 179 M 146 W and Sanath 255 M 177 W. While Jayasuriya is a fantastic part time spinner he is certainly not top five material. Latter top ten perhaps though.

...The Rest
Even my personal hero has a better record currently than Sanath, taking 36 wickets @ 33.52 from 29 matches, the only blip on his radar being an economy of 5, mainly due to him often being used in powerplays or the death.
I reckon anyone mentioned on my list is pretty hard strung not to get a spot in this poll, Vettori and Salqain's exclusion in particular (though Vettori does have a rather shocking WC record to date).
