In the Hyman situation we see the fallout of the Leafs top-heavy approach to cap management.
1) Hyman walks because the Leafs can't afford him and is replaced by a cheaper (but less effective) option in Bunting.
2) When Bunting becomes a free agent he walks and is replaced by Knies at about the same cost but with lots of upside.
3) If Knies lives up to that upside before his ELC is done, he'll be in line for a significant raise and the Leafs may not be able to afford him either.
So, by sticking with this core four and rolling the Brinks truck up to their door each time they need a new contract the Leafs have been forced into a revolving door with virtually every other position on the team outside of LD1 with Reilly.
Worth noting the Leafs COULD have afforded to keep Hyman, they just opted to spend the money elsewhere (to some controversy).
Knies doesn't have arbitration rights yet, they can keep him on the cheaper end for the foreseeable future.
And on the flip side, the Leafs revolving door of support players has as much to do not wanting to keep certain players long term than because of cap. Guys like Bunting had worn out their welcome (Mirtle says they didn't even try to start negotiations with his agent), but they have always found money when they wanted a guy - Brodie, Muzzin ect all locked in for 5 year deals.
Hyman is probably the only guy who I think folks really missed in not extending
