I think in free agency are only three choices left...Semin, Doan and maybe Huselius.
I am not a big fan of Semin but he is pretty good player. Bad thing about him is that his cap hit will be huge (even after bad season I think it will be around 6,5 million).
Doan for right price is good choice for few years and Huselius could be available for cheap, but he played in only 41 games in last 2 seasons.
Anyway In Lou I trust
