They could be options, sure.
The team has not revealed how it plans to attack (or not) any of those areas yet.
I know lots of people are waiting to hear about it.
One one hand you could make a case the Cardinals are going to come out swinging to give Marmol his best chance of winning big after the surprise managerial change put a spotlight on the front office.
On the other hand, Mozeliak when asked recently reiterated the philosophy of the team is draft-and-develop and give chances to internal options, so maybe he was suggesting what is to come this offseason.
I'm not trying to be vague, I just don't know at this point.
And no one knows what the 2022 season is going to look like, either, with CBA fiht looming.
