Johnson hasn't lived up to any hype yet.
be the stud DT we are used to (Brockers)
Funny because as a redshirt sophomore, and starter, Brockers had 10 TFL and 2 sacks. So Anthony, playing less snaps, and a year younger had the same numbers this past season. If Anthony hits your definition of "hype", he will have more accolades than Dorsey.
In fact, here's how the other guys you mentioned played in the second year at LSU:
Williams: Starter: 6.5 TFL 4 sacks
Lavalais: Starter: 5 TFL 1 sack
Wroten: JUCO Transfer: SR season: Starter: 10.5 TFL 6 sacks
Nevis: Reserve: 5.5 TFL 0 sacks
Dorsey: Reserve: 4 TFL 3 sacks
Johnson: Reserve: 10 TFL 3 sacks
