According to a recent report, the Leafs should absolutely target the Minnesota Wild's number two goalie, Marc-Andre Fleury.
With his vast experience, leadership and talent, he could be the missing piece in Toronto. He definitely couldn't do worst than Samsonov.
This season, he hasn't been playing at it usual level. At 39, it's clear that the end of his career will come soon. However, his 6-5-2 record, 3.16 GAA and .892 SV% don't reflect his talent. The Wild has been struggling this year and he isn't to blame.
