Things I know about Arias:
He isn't Felix Fermin. He isn't ARod or Bo Bichette, either.
If he (or Rocchio, etc) can average a Chris Taylor line with their defense the team will be in a great position.
The org needs to trust what their scouts and development team "see" and forecasting models project and pick who they envision succeeding. Play "that guy" 500 ABs. We all know keeping Voldemort at SS stunted growth of the youngsters this year.
If that guy is Arias, platoon him out when better than average LHP are starting. Have him work out the LHP issue with #3-5 starters.
Baerga had 1,500 MLB ABs to look at by the end of his age 23 year. Jose with over 1,100. Arias has under 400.
The people who are swearing Arias is only worth a bag of balls and used Victus bat, look at Dansby Swanson. He didn't replicate his rookie numbers from 148 AB his age 22 season until 1,800 ABs and four years later. People around here bitch about Tyler Naquin had a good couple of months with the Reds, Nolan Jones' numbers with the Rockies are inflated by a .375+ BAbip and King Kong Palacios has a good 45 ABs. I can only imagine the wailing if Arias was traded to the Pirates and became their version of Swanson in '26.
If Arias doesn't work out, figure out which one of Rocchio, Freeman, Tena, Brito to pair with Andres going forward. Rocchio would be 24, Freeman 25 starting the '25 season. If they pick Rocchio to get the 500 ABs next year, Arias would still be 25.
