The only issue with bringing in an outside GM is the risk of them wanting to over-haul the roster. They'd want their own pieces and create their own puzzle, kind of like what WR did. If this was the start of the rebuild, where anything was fair game, then, yeah, bring in someone who knows what he's doing.
This is why I say give Bowler a couple of seasons to see this rebuild through, see how he finishes off the roster, etc. If it doesn't work, bring in a new, experienced guy for a total overhaul.
A team poised to make a run in 20/21 but has some work to do to get the final pieces in place, who do you trust that to?
A proven, experienced GM with some sort of track record
Or
An unknown entity who's not proven anything at this level and who's biggest qualification is loyalty to the current owners in past positions
We don't know how Bowler will do and hopefully he does well but at this point in time a proven track record would be best over an unproven one. Adding in everything else that's gone on an outside influence/voice would provide better optics then doing the same types of things that pissed off the fanbase over the now failed sale.
It's nothing against Bowler, it's the thought of seeing another rebuild stretch out to five/six/seven years when their window should be opening now.
An outsider with the autonomy to do his job could put his own mark on things and strip things down but with a roster on the verge of competing the question is why?
A roster with good young talent.
Assets to use but need to be topped off.
What experienced GM wouldn't want to walk into a ready made roster needing to be tweaked?
If there is concern of an outsider stripping things down shouldn't there be the same concern about Bowler? Unless he doesn't have the autonomy to do the job which would bring this back full circle, is he simply a yes man?
It's all speculation and until we start hearing news about signings/trades under Bowler's direction we really won't know how much autonomy he'll have.
Do we see small moves to resolve the numbers? Do we see bold moves that can have a major impact? Do things basically stay the same and things are simply played out until ownership has a major announcement about the future?
Until such time as there is activity to discuss we don't know but we've all seen enough to know there are potential concerns at the moment.
