Outside of trading Drai/McDavid, he had no way to improve, other than fill in some scraps and cross his fingers. Holland is suffering from previously bad GM decisions just like BA. The difference in Edmonton is Tip did it with mirrors outside of the top 2 players, hid the lack of depth, but in the playoffs, teams have more time and are better prepared, your weakness gets exposed. We had RT, he couldn't hide anything
Oilers will need to trade Drai to really improve as a team and add the depth they need. I am sure Holland doesn't want to do it but he might be forced to now. Oilers would have been blown out if not for Smitty
