When Matt Harvey talked Terry Collins into sending him out for the ninth inning of Game 5 on Sunday, it made for one of the most compelling moments of the postseason.

After watching the Kansas City Royals rally for two runs in the inning en route to their second World Series title in franchise history, Collins' decision to stick with his starter could haunt him for years to come.

"I'm going to second-guess myself for a long time, but I truly believe you've got to support your players once in a while and that kind of heart and that kind of desire is hard to find," the New York Mets manager told Ken Rosenthal of FOX Sports after his team's season ended with a 7-2 loss. "I'd have taken him out and we’d allow the runs and it would have been the wrong decision anyway."

Collins, who replaced his ace with Jeurys Familia after the first two batters of the inning reached base, said it was impossible to say no Harvey after all the right-hander had been through this season.
