I don't think you really could have hoped for a better bounce back season than Smith has been having. He is producing career best walk and power numbers, while also having significantly cut down on his strikeouts at the same time.
Smith didn't really have any questions about his defensive ability, his ultimate ceiling was all based on whether he could improve his results at the plate. His success doesn't appear to be based on an unsustainable BABIP hot streak, and seems to be due to improved approach and plate discipline. This bodes very well for his chances to translate some of this into major league success. Smith may be a little old now, but you need to factor in the lost season due to covid.
