As good as the Cubs have been since a 3-8 start, some really bad vibes are surrounding this team.

Last week was the epicenter of it.

The Cubs announced on May 8 that Ben Zobrist had left the team for personal reasons, and there was “no timetable for his return.”

Reports started surfacing that his wife, Julianna, had taken down all photos from her social media site that included him and had suspended her Twitter page completely.

You might remember that Zobrist missed a few days of spring training to attend to personal matters, but that happens all the time in March and no one thought anything of it.

Now, it’s a big deal.

These are people who have a very public relationship: They live just a few blocks from Wrigley Field (Ben often rides his bicycle to home games), his “walk-up song” is Julianna singing the chorus of “Benny and the Jets” and they have written a book together on marriage.

I’m praying for them.

The Cubs also activated Addison Russell from the minor leagues, where he had been working out in preparation for the end of his 40-game suspension for violating baseball’s policy on domestic violence.

I have been a defender of this player’s right to a fair trial in the court of public opinion. No, he is not a natural public speaker like many of his teammates. Yes, he is probably the Cub the fans know least about. And because of those things, I have defended the handling of his 40-game suspension by himself and the Cubs organization.

The man was accused of physically abusing his wife. He paid a price for that, and now he should get a chance to prove what he learned from that, and to show that he isn’t “that guy” anymore.

Well, it took about 20 minutes during two sessions in front of the media last week to prove himself still arrogant, defiant and very unrepentant.

Russell was called up May 8, and because of Zobrist’s situation and injuries, he was immediately inserted into the lineup for that night’s game against the Marlins. His name was booed when it was announced with the lineup before the game, and he was booed as he strolled to the plate for the first time. The sentiment was noticeable, but it would be hard to give a percentage of how many fans were voicing their displeasure.

One thing is for sure — Russell heard it.

“I’m a baseball player for the Chicago Cubs,” he said after Wednesday’s return. “I’m one of the dudes in this clubhouse. I’m one of the guys who goes out there and puts his [body] on the line. We do it because we love it. We want to win, and we want to bring another championship to Chicago. And if hometown fans want to boo someone that’s trying to help bring the team a World Series again, then that’s on them.”

Well, OK then! We needed to hear phrases come out of his mouth that included the words “sorry” and “regret,” and we got none of it.

He certainly is not the first athlete to wrap himself up in the “I don’t care what anyone else thinks” security blanket. But 99% of the ones who have used it before him DO care what others say and write about them. They respond to unasked questions in press conferences. They fight back on social media. Oh, be perfectly clear — they care very much about it.

It’s one thing to be booed and jeered on the road. That can be a motivating thing for a player. But at home, you want to think those people love you no matter what. Cubs fans, at least some of them, sent Russell a message the other night and he received it, but he did not accept it.

The truth is, the Cubs don’t need him on the field or in that clubhouse. They might have the best defensive infielder in the game already in Javy Baez. Addy is a .220 hitter at-best with very occasional power and is an average baserunner. The Cubs have people who can give them that without the headaches. I think it’s time to see what kind of interest is out there for a guy like Addison Russell.

A couple of 24th round draft choices and a bucket of batting practice baseballs seems like fair market value.

But how good are the Cubs right now? Through all of this, they won three games in five days on walk-off home runs.

It’s going to be an interesting summer.
