Should Hanwha sign FA players?

I don't know much about baseball.
It feels like all the top prospects we've brought in over the last few years will have to start from scratch again,
we'll have to wait until the latter half of next year to see Moon Dong-ju after his rehab,
and it's uncertain whether Moon Hyun-bin, Heo In-seo, and Park Jeong-hyeon (batter) will perform as well as they did this year.
It's also a question mark how Oh Jae-won and Jeong Eun-won will perform...
We also need to see if FA signings like Eom Sang-baek can bounce back...
We don't know which candidate, such as Ryu Ji-hyeon or Lee Dong-wook, will become the Hanwha manager,
but we'll have to keep an eye on the FA signings as well.
