His defense is weird. Most of the metrics have rated him fine at 1B since he started playing it in 2020. The exception is OAA which thinks he SUCKS at 1B the past two years even though the other metrics still think he's okay. If you look at his plot the past two years it looks like he sucks when he has to make a play where it involves feeding the pitcher: https://shorturl.at/IcI48. That seems to track the eye test.
But otherwise his plot looks ok, including on plays where he has to move back (also tracks the eye test as he seems ok when chasing down pop ups). His sprint speed is close to league average and his arm is well above average. Maybe he would be be okay in LF? Heck, maybe he's even better at 3B than he is at 1B. He has the arm for it and he doesn't have to feed the pitcher. Metrics were fine in a SSS.
Sounds kind of crazy but we are now living in a world where Spencer Horwitz is an above average 2B so I would definitely consider Vlad in LF.
