Date	Question	Answer
2019-05-17 16:00:00 (link to chat)	Scenario: CWS trade Colome and Herrera (or he's just ineffective), who's your target? Where are you on Aaron Bummer? Cheers (KC from Kaufman)	Bummer's probably the arm I want by default, unless Nate Jones magically finds sustained health. I do wonder if Minaya gets the next shot though just because he's been the closer in some past White Sox iteration that I can't even remember anymore. (Mike Gianella)
2018-09-04 19:00:00 (link to chat)	Will the White Sox bullpen be stacked with power rookies next year? And what will the rotation look like after Rodon, Kopech, two guys and Giolito? (Alex Prettyface from Gundergunder)	This is part of why I foresee a path to 2019 contention as hinted at above, even if it's unlikely--and we've seen how conservative teams have gotten when playoff berths appear to be less than 50% in the offseason. I'm bullish on both Ryan Burr and Ian Hamilton, Jace Fry has already had an excellent 2018 in the majors, and there's reason to think Caleb Frare is already here and effective. There's always attrition in the bullpen, but there's just so many guys here who have flashed ability to be excellent back end options, and it's a strength of the organization. Covey has looked really good in short bursts, Carson Fulmer will have an offseason to prepare solely as a reliever, some of the guys who don't make the rotation, like say, Jordan Stephens may be effective in that role. Nate Jones might come back, Zack Burdi should be in the majors at some point next year, and even the newly promoted Jose Ruiz has an extremely live arm. Kodi Medeiros is still getting to try starting, but I think he could be a late inning reliever as well. Aaron Bummer is a guy they like a lot. All of these guys individually are risky propositions based on being relievers, health, ability, etc. But collectively I think they just have a flood of in-house options such that this could be a big strength as soon as next year.
