I believe Timmons has leap frogged Benn. This team would be Stanley cup favorite. imo Big question is the package enough?

You're right about Timmins, and Leafs would lose him on waivers if sent down. Leafs seem to have a good seven deep Dmen. Even Holloway, Mete can fill in if necessary.

I have Roni as a untouchable for Leafs and Topi too plus Knies.

You can't expect to acquire any good players if you make all your prospects untouchable...

3 guys are all of our prospects?
I'm just stating my opinion but every team has untouchables

If Blues pull plug on the season, they should accept that

Not sure I agree that Timmins has leap frogged Benn on the depth chart - especially come playoff time when they'll be looking for Benn's heavier game.
I do agree they will probably lose him if they put him on waivers, which would be a shame. But I think if that's the risk you have to take to swing for the fences with ROR & Tarasenko, it's worth it.
Losing TImmins is not ideal, but it shouldn't hurt all that much with guys like Holloway, Mete, etc. in the pipeline.
Plus, there's always injuries, so you may not even need to waive him if there are guys on LTIR during the season. (And there's no cap once playoffs start).
