Yup.
I picked him up in almost all of my leagues but when I tried to get him in this league, during the end of week 16, adds/drops/waivers were locked, and accordng to the rules I thought my chances to pick him up were lost until just before next season?
As I already mentioned, adds/drops on RT is open right now and so my guess is that someone just forgot to lock adds/drops on RT?
