guessing he is meaning the "Star position" slaughter played on certain teams to be more athletic on spread and option teams
Yes, he can be utilized as a big safety or small LB depending on the type offense we play. Big safety against spread teams especially those with move TE's that have become the rage. He's the kind of guy teams would like to have play against the Eiferts of the world. Also can drop down to LB like Slaughter did against the option teams like Navy, AF, Georgia Tech, etc. A good DC can find different ways to utilize his skill set.
