I'm not going to pretend I have the slightest clue who this guy is, or that I've ever heard of Tarleton State. I'm just going to count on the Saints' ability to find talent in the smallest of schools with Junior Galette (Spellman), Jermon Bushrod (Towson), Marques Colston (Hofstra), Akiem Hicks (Regina) etc… Rufus Johnson did have 10 sacks in 9 games against bad competition last year so I guess that's worth something. He's 6'5", 272lbs, so safe to say he measures very well for a 3-4 end.
The only site that has a write up on him is NFLdraftscout.com
With this pick the Saints are done with their draft picks unless they make a trade into the 7th round, so they'll start recruiting remaining rookies in hopes they go undrafted.
