Just for fun, a look at how the 2016 Cubs are doing in 2023...
Retired/out of baseball: Miguel Montero, Ben Zobrist, Dexter Fowler, David Ross, Matt Szczur, Chris Coghlan, John Lester, Jake Arrieta, Jason Hammel, John Lackey, Travis Wood, Hector Rondon, Albert Almora, Trevor Cahill, Justin Grimm, Pedro Strop, Adam Warren, Joe Smith, Clayton Richard, Felix Pena, Neil Ramirez (only looking at Cubs position players that played 20 games in 2016 or are Kyle Schwarber or as a pitcher had at least 8 appearances)
Anthony Rizzo, Yankees: .244/.332/.381/.713 and 0.9 bWAR (too lazy to do this on FG)
Addison Russell, Kiwoom of KBO: .286/.339/.400/.739
Kris Bryant, Rockies: .252/.337/.380/.717 and -0.5 bWAR
Jorge Soler, Marlins: .244/.339/.506/.845 and 1.3 bWAR, 2023 All-Star
Jason Heyward, Dodgers: .251/.350/.465/.815 and 0.9 bWAR (Dodgers made some adjustments but more importantly have given him almost no PAs against lefties)
Javier Baez, Tigers: .227/.264/.341/.604 and 0.7 bWAR (defense still plays)
Willson Contreras, Cardinals: .242/.339/.424/.763 and 1.5 bWAR
Tommy LaStella, Mariners: .190/.292/.238/.530 and -0.1 bWAR
Kyle Schwarber, Phillies: .187/.313/.440/.752 and -1.0 bWAR
Kyle Hendricks, Cubs: 3-4, 3.38 ERA and 1.0 bWAR in 11 starts
Mike Montgomery, Oklahoma City (AAA): 1-1, 3.34 ERA in 8 starts
Carl Edwards Jr, Nationals: 1-3, 3.69 ERA and 0.6 bWAR in 32 appearances
Aroldis Chapman, Royals/Rangers: 5-2, 2.04 ERA and 1.3 bWAR in 37 appearances
Spencer Patton, Athletics: 0-0, 6.75 ERA and -0.1 bWAR in 4 appearances
Rob Zastryzny, Pirates: 1-0, 5.29 ERA and -0.3 bWAR in 18 appearances
Total of 6.2 bWAR with 1 win coming from a current Cub.
Not really making a point with this, just wanted to go back and see where everyone is at. Really no one from the 2016 team is a star in 2023 except Soler who is literally an All-Star this year. Would not have expected that to be the case just 7 years removed from a 103 World Series winner with a young core in their early 20's.
