If you thought fans were excited when Jason Heyward chose to sign in Chicago, just imagine how the Cubs must be feeling.
Joe Maddon called Heyward "a beautiful man," throughout the 2015 season when he watched the dynamic 26-year-old outfielder star for the St. Louis Cardinals.
Theo Epstein's front office took note of the way Heyward played against the Cubs all year, but it was a particular at-bat in the National League Division Series that really caught Epstein's eye.
In Game 3 at Wrigley Field, Heyward got a breaking ball from Jake Arrieta - the best pitcher on the planet at the time - off the plate outside and drove it to the left-field bleachers.
"It was a swing I hadn't seen from him up close in person before," Epstein said. "It shows a real sophisticated approach and an ability to make and adjustment like that against one of the best pitchers in the game.
"A lot of our players and staff were buzzing about that swing in the clubhouse after the game. You couldn't help but envision maybe some of the damage he could do playing at Wrigley Field on a consistent basis."
Heyward has had success at Wrigley Field throughout his career, sporting an .898 OPS (on a .311/.376/.522 line) in 25 games at "The Friendly Confines."
He also enjoyed playing in Chicago during the postseason, going 3-for-6 with a double, that homer off Arrieta and a pair of walks in a limited sample size.
That being said, Heyward only hit 13 homers in the regular season, after hitting 11 in 2014. In fact, he's only topped 18 homers one time in his career - clubbing 27 with the Atlanta Braves in 2012.
The Cubs are paying Heyward like a middle-of-the-order slugger ($184 million), but the fact of the matter is, he may never develop into more of a power hitter.

That doesn't mean the Cubs can't hope, however.
"I think it's in there," Epstein said. "He has hit 27 home runs before. There are a lot of players who don't find their consistent power stroke until they get to this age - 26, 27, 28."
Epstein then compared Heyward to another right fielder - Dwight Evans - who didn't find his consistent power stroke until his late 20s with the Boston Red Sox.
Up until age 26, Evans managed just 65 homers over six seasons in the big leagues, topping out at 17 in 1976 at age 24.
However, Evans hit 24 homers in his age 26 season, launching a 12-year run where he hit 301 longballs, averaging 25 per season and hitting at least 20 in every year but one during that stretch.
"Obviously for Jason, it's in there," Epstein said. "But his frame and his batspeed, how far he does hit the ball when he gets ahold of one and his ability to manipulate the barrel and opposite field home runs in parks that allow it like Wrigley Field, I think there's more power in there.
"But the beautiful thing about this is he doesn't have to hit for more power than he already has to really help us win a lot of games because of what he brings to the table defensively, on the bases and his on-base skills.
"Now, you add consistent power production into the mix and you're talking about one of the true, true elites in the game. We'll see how his career evolves.
"But he doesn't have to do more than what he's already done. His approach and how hard he works and wants to get better and the growth mindset that he has, he could put it all together."
Heyward was an interesting free agent, given that most players who hit the open market are on the wrong side of 30. But he is a young player with his prime years ahead of him and even though he isn't a consistent power threat yet, he was still considered the top position player in the free agent class.
Heyward appreciates the way this game has developed and everybody can understand there's more to a player's skillset than just batting average, home runs and RBI.
But he also believes - like the Cubs - that there's room for his game to grow.
"I feel like I'm not done," Heyward said. "I feel like there's more in there. I said that at the beginning of spring training in 2015.
"I feel like I took some strides going forward and getting back to some things that I used to do when I was 19, 20 years old. I want to see what I can do to make the most of that and continue to build off this past year."
