Recently I spoke about the possibility of Indy Superstar Ricochet joining the WWE and being immediately bound for big things in the company. However, he isn't the only top Indy star that WWE has on their radar to possibly sign when they become available. Tommy End a top International star from Germany has been on the companies radar for some time and though I have never seen him wrestle in the ring I have heard various people praise his skills.
Speaking of Ricochet WWE is also looking at Angelico from Lucha Underground who is one half of the former World Trios Champion in Lucha Underground so that would cause a problem. Angelico I do is a highly skilled in ring talent and I do believe is the member of the Lucha roster that has taken various leaps from the roof of the "Booking building" which is the big building in the Lucha Underground arena. (By the way if your talking dangerous Shane McMahon's dives back in the day were a lot more high risk and were incredibly more dangerous then any dives today.)
Currently of the people that are on the WWE's radar to sign only one person actually has and that is international women's wrestler Nikki Storm. The addition of Storm would further add to what was dwindling depth in the NXT Women's division. Which will be a welcomed addition, and just to notes Nikki should be starting with the company soon as they are just working out some final details right now.
