Dana has been mostly good with talent evaluation so far, if Matthews hits it’ll validate him a ton more.
Brice is everything they expected him to be. A very high ceiling player that has a low floor. If he learns to make contact consistently, he will be a star. If he doesn't, he won't last long in the league.
If he has enough glove to be a plus defender (he's got the agility and arm), it won't matter how much he strikes out as long as he gets on base a bit. And hits for power. And takes some free bases. There's no reason a guy like that can't be a part of your lineup.
