I don't think this'll effect the Oiler too much. The Oiler aren't rocking any super large contracts (most teams have 2-3 contracts with higher caphits that the Oilers). And outside of McDavid, they don't have anyone that should come in higher than 6 over the next few years.
The Hawks are in troble in this system. 21 million to just two players, and near 45 million to their top 6 highest paid (Toews, Kane, Seabrook Crowford, Keith, Hossa). By contrast, the Oilers will likely have arround 12mil invested in their highest 2 contracts and arround 35 after totaling up their 6 highest paid.
The question becomes when would this be? The Oilers ideal window would be within the next 3 years, before McDavi'd and Nurse's ELC expire.
Following the old rules... "Choose to protect either nine forwards, five defensemen, and one goalie or seven forwards, three defensemen, and two goalies". All ELC's are inelegiable...

The Oilers actually come out of this pretty well
