07:25 AM ET 06.14 | Alain Vigneault may well be the Rangers' clubhouse leader in the race to take over the club. That, of course, excludes the other leader in the clubhouse named Mark Messier. This is the state of the Rangers' search for a coach that paused yesterday following Vigneault's visit on Tuesday with general manager Glen Sather. ... Sources from the Boston area where Brian Leetch makes his home told The Post the Hall of Fame defenseman would likely join the Rangers' coaching staff as an assistant if Messier is hired. The Blueshirts would need to hire a technocrat with meaningful NHL coaching experience to complement Messier and Leetch should Sather opt to go in that direction, one that would seem a far riskier one than hiring Vigneault.
