I think your definition of complicated differs a tad from mine. Adding Fowler to that list just means you protect Fowler. It's that simple. Just because you can't protect a lesser defenseman doesn't make it more complicated. Every team is in the exact same situation. If you aren't at risk to lose a pretty decent defenseman, after naming 3 protected ones, it's because your blue line is shallow.
Would the Ducks protect Fowler?
Bieksa is under contract for the next two seasons with a NMC.
If they don't buy out Bieksa they have to protect him. Do they also protect Lindholm and Vatanen, leaving Fowler exposed and possibly gone for nothing?
Do they avoid losing Fowler to expansion by buying out Bieksa, or by trading Fowler for the best value they can get?
If they don't get a good enough deal for Fowler, does it come down to buying out Bieksa or exposing Fowler?
When is Fowler's value the highest? Now, while he has two years left, or approaching the expansion draft when he has only one season left under contract and is essentially a rental?
If Fowler's trade-value diminishes as the expansion draft approaches, does that create pressure on Ducks' management to trade him sooner rather than later?
If the best deal available for Fowler is not enough, and they buy-out Bieksa to keep Fowler, would the Ducks then re-sign Fowler to a new contract when his present deal expires?
From the Ducks side it doesn't sound all that simple to me, except in the sense that if they aren't able to trade him for good value before the expansion draft things get more complicated from there.
I think your definition of "simple" might be a little different from mine as well.
The Ducks' predicament with Fowler doesn't sound too simple to me.
