The linebacker with the most sacks in an NFL season is Justin Houston of the Kansas City Chiefs. He finished with 22.0 sacks in 2014.
Reggie White (Green Bay) and Darnell Dockett (Arizona) with 3 sacks each.
There isn't really a record kept for fewest sacks in a season by a player, as there are thousands of NFL players who have not had any sacks. Michael Strahan holds the record for most sacks in a season, at 22 1/2.
