I've seen double doubles pretty consistently as of late, but I realize I haven't seen a triple double in forever.  I myself in my 40+ seasons have probably only had two-three players record them (though I had one who I believe recorded three or four on his own), but I think all of those players were pre-potential. 

Just wondering what the most recent triple doubles other coaches have noticed lately consisted of and how recently (or better yet, how often) they occurred (tend to occur).
