I agree with all of that. I think Gurriel's emergence has been the thing I've liked the most. He's not this good obviously, but even if he's league average or better with the bat and glove, that's a capable starting OF on this team. If he's better than that, then great. I think Jansen will get better. He's already good with the glove and I feel his bat will eventually turn it around. I really like the Bichette-Biggio-Vlad-Gurriel-Jansen group. It would be nice to add a CF in there who can join them. Haven't completely ruled out Alford but he's getting closer to being an afterthought despite his recent hot streak. He really needs to be up and playing everyday instead of Teoscar.
The bad was mentioned in the OP. SP depth sucks. Haven't gotten any contribution yet from AAA starters except Thornton. All the fringy/undervalued pick ups by Atkins, or fringy inherited prospects, have flopped (Drury, McKinney, Teoscar, Brito, Tellez, etc). Gurriel turning into something has at least taken some of the sting away.
The Grichuk extension was unnecessary, although his performance this season really doesn't matter all that much. But 2020 and beyond he needs to be effective. I would go into this deeper, but Brownie is already triggered and likely in tears just by reading Grichuk's name mentioned, so I'll expand another time.
Atkins has been a mixed bag so far, but like I said before, the trade deadline will either further prove he's not the guy for this role, or it could be his redemption. He needs to hit a grand slam at the deadline. Right now I really just trust the team's drafting and international signings. That could change with a good deadline haul.
