From the UCi website right now:
UCI Road Rankings
Individual ranking:
Fuglsang is 11th with 1775 points.
Team ranking:
Uno-X is 25th with 1203 points.
Total:
2978 points.
Cofidis is 15th with 2689.
Arkea is 16th with 2595
TDE is 20th with 2080 points
So yes, as of the standings today, signing Fuglsang would bring Uno-X to 15th, and provided Alpecin goes WT next year, that would make them the top Pro team.
And sure, none of us know how many points anyone makes, the rest of the year, so things can change, but that is how it stands right now.
Either way it's a moot point, because IF they signed Fuglsang, he would be part of a group of new riders signed, each bringing points, to ensure participation in the Tour next year - if not there would be no point.
