Miguel Montero picked the worst possible time to second-guess the way Joe Maddon handled the bullpen during the World Series and communicated with his players — a radio interview on the same day (!!!) as the championship parade through the streets of Chicago and a Grant Park rally that may or may not have been one of the largest gatherings in human history.

The cameras also caught Montero popping off at a time when the Cubs were hovering around .500 and running out of ideas to spark the defending champs. So team president Theo Epstein didn’t hesitate to DFA Montero in late June when the veteran catcher ripped Jake Arrieta for letting the Washington Nationals run wild on the bases. Eating almost $7 million in salary and shipping Montero to Canada became another button to press to shake up the clubhouse.

But Montero also came along at exactly the right time for Kyle Hendricks, who had 13 major-league starts for a last-place team on his resume heading into the breakthrough 2015 season that set up last year’s transformation into an ERA leader, Cy Young Award finalist and World Series Game 7 starter.

Montero doesn’t deserve a tribute on the video board when the Toronto Blue Jays come into Wrigley Field this weekend, but he also shouldn’t be remembered only as a loose cannon or a cartoon character.

“Miggy was huge for me,” Hendricks said on this week’s Cubs Talk podcast. “I know he didn’t go out the way he wanted to. He’s even texted all of us here. We have the utmost respect for him around this clubhouse. We know who he is, the teammate he was around here.

“For me in particular, he was probably the biggest influence right when I came up, from the catching side. He taught me a lot about pitching, especially at the big-league level. (He made) me feel comfortable at the big-league level.

“My development, I think, sped up a lot just because of him being around here, his experience, how much he knew the hitters, his feel and his ability just to talk to you. He could sit down and just have a conversation with you whenever.

“I owe a lot to him. And I’m excited to see him back here.”

The Cubs knew they were getting the good, the bad and the ugly when they traded for Montero during the 2014 winter meetings in San Diego, where they also closed the $155 million megadeal with Jon Lester and dramatically reshaped the franchise.

The Cubs wanted Montero’s edge, which only sharpened as he got stuck in various three-catcher rotations. But Montero welcomed Kyle Schwarber and Willson Contreras into the clubhouse, delivered a wake-up call to Albert Almora Jr. during a rehab assignment at Double-A Tennessee and worked with Arrieta as he blossomed into a Cy Young Award winner. Montero also became a bilingual intermediary last summer when Aroldis Chapman initially refused to talk to the media after making his Cubs debut.

After handling so many different personalities and styles with the Arizona Diamondbacks — everyone from Randy Johnson to Dan Haren — Montero made the case that Hendricks didn’t need to throw 97 mph to thrive when he could nail the edges and deceive and outthink hitters with movement and sequences. Street smarts from Venezuela and an Ivy League education became a great match.

“He always had that confidence in me, from Day 1, when I showed up in this clubhouse,” Hendricks said. “He caught my bullpens. He kind of saw what I could do with the baseball. He probably had more confidence in me than I had in myself when I first came up.

“That’s just how it is. You’re trying to find your footing. He just kept preaching that to me, telling me what he saw in me, what I could do, the ability I had against these hitters. And then we went out there together and kind of saw it happening.”

One Arizona official who knows Montero well theorized that he — like any former All-Star in his mid-30s nearing the free-agent market — simply had trouble coming to grips with the reality that he was no longer The Man.

Even if you may be right on both counts — and no matter how fast Montero patched it up with Arrieta — the backup catcher can’t blast a star manager and a star pitcher like that.

“It was too bad to see him go,” Hendricks said. “But that’s just baseball. That’s how it goes. You got to learn what you can from who’s around while they’re there and then move on. That’s just the nature of the game.”
