I couldn't find anything for 2008, but from 2009-2014 Bo Pelini's special teams: allowed one total kick return TD in six years, were ranked in the top 25 in total opponent kickoff return yardage allowed per game in four of those six season, and scored eight punt or kick return touchdowns. They also blocked 16 kicks in that span (though six of those came in '09 with Suh so I'm not going to credit him with that too much). His punt coverage units were pretty meh but overall he was a good special teams coach (in addition to recruiting and developing good specialists).
