Brett Hull currently has 33 goals with 5 games remaining. If he gets 35 goals this year, a clause in his contract would give him an extra year in Detroit next year for 4.5 Mill.

However, Hull has nixed that contract and agreed to a 1 year 5 Million dollar contract to play in Detroit again next year. After they win the Stanley Cup again this year; Detroit will be poised to make it 3 in a row next season.

So he's a free agent after next year?

Yes.
