From Greg Logan of Newsday:
Multiple team sources from the locker room to the front office blamed Nolan for ignoring advice from his handpicked assistants regarding the defensive system the Islanders used and the power-play setup. Miroslav Satan, who scored 17 of his 35 goals in 2005-06 playing down low on the power play, rarely was used that way by Nolan and his production declined to 27 goals, then to 16 last season.
A person close to one top player accused Nolan of "mismanaging his assets." The person added, "Various people on the team caught Ted Nolan in outright falsehoods."
