I think standing pat or a couple of small additions are the worst moves they could make.
Stand pat, hope everyone who can return does and go into next season hoping everyone takes a big enough jump that they don't have to add since they will have fewer assets at their disposal to add with.
Make a couple of small additions and hope to get to, and out of the second round and hope, like standing pat that everyone returns, probably have even fewer assets to do something with next year.
Both lead to years of mediocrity.
Be bold this year and go one of two ways.
Go all in and accept another long rebuild since it would cost most of what they have.
Move their big pieces, add youth and picks and set themselves up for multiple years of success with a ton of extra picks and adding some good/very good young players that likely doesn't change where they finish once other teams load up.
Rychel's best year as GM was 07/08. He had a team exceeding expectations, like this year decent assets and what did he do?
He sold, added young players and picks and gave us 08/09 and 09/10 with the potential for a third year in 10/11.
Standing pat won't do that and neither making a few small additions.
Bowler needs to be bold, one way or the other. If there's a potential buyer in the background, if it were me I'd want a team built for the future, not one that is sitting at the start of a rebuild or slated for years of mediocrity.
If this group is in it for the long haul, buy and deal with a rebuild if they want. If there's a buyer or they really want to build a long term competitive product, sell your 2000s and have something serious to work with.
Stand pat and continue with the same results year over year that we're all tired of.
