I dont know how they faired int he Draft but there are quite a few RMs in the NFL.
You have Jordan Devey who served with my cousin in Costa Rica.
Cody Larson who played for Broncos
Will Tukuafu who plays for the Seattle
Trevor Reilly who plays for the Jets
I am sure there are others not listed but those are off the top of my head.
Oh Just remembered Paul Kruger, I think he is an RM.
