I like Herbie & he's a top midfielder to have at Division 1 level. It's just that he lost his discipline v Lincoln, picking up a needless 2 match suspension for mouthing off. Then for taking 15 minutes to get off the pitch when we were 0-1 down, he won the BBS poll for Dick of the Day https://barnsleyfc.org.uk/threads/diick-of-the-day.328839/page-2 When he came straight back in to the team v Cambridge, he played badly but hard to hold that against him personally when there wasn't a POTM candidate. It's as the gaffer said in a recent interview, there's stuff we're unaware of behind the scenes & we pick the best team to secure the 3 points every time. There's no doubting Herbie's ability, so could be a physical niggle or a lack of application (between the ears). As to my opinion on the OP, if he's done well in training since Saturday, I think he'll start but would say it's a 50:50 & I trust Collins' judgement on that.
McAtee also pressurises goalkeepers. He can miss easy chances, but also score great goals, and his enthusiasm is vital to the team. He has to start every game in my opinion, and as our striking options are not as good as our midfield options, I would always play him up front.
There can't be many seasons where we've been in the playoffs yet every single player has been criticised or worse.
