3 more years (after this one) at $6.5M. He's playing 2C for a thin Blues forward-group, but could play any forward spot in the middle-6 of a contending team. Physical, responsible, will drop the mitts and put up points. Cup-winner & current captain. Ideal blend of grit, skill and leadership for teams with championship aspirations. With cap rising, maybe the Blues would be willing to retain $1M-$1.5M/year; he'd almost certainly get $5M/year x 3-years if he were UFA this summer, so I wouldn't think the contract would be too painful.
Blues pipeline is overflowing with forwards, which is why he may become expendable. Would be looking for draft capital or NHL-ready young defensemen already drafted.
Teams like Winnipeg, New Jersey, Toronto or Carolina would seem to make sense from an outsiders perspective.
