Scraping web data

New to the rvest package and trying to scrape data from a website and having issues. (Might help to look at website for reference, Cameron Johnson College Stats | College Basketball at When I try to pull a name from the top like Cameron Johnson or a number value like 11.2 under PTS I have no problem, but when I try to pull something from one of the specific tables using the selector gadget it is not bringing any values back. I am not getting an error. It just brings no value. Any suggestions would be greatly appreciated because I am stumped!

offrtghtml <- html_nodes(cj, '#players_per_min tfoot tr:nth-child(1) .right:nth-child(25)')
offrtg <- html_text(offrtghtml)
