Scheel leaving as a junior should been planned for, but no replacement was there. Feeney was brought in for an injury to Thome, after they tried to get Vernon to come in (halfway through the season). Hoby was too far out to replace Scheel.
I'll say the problems with the goalie pipeline go back to Tomek, Karki and Rowe, Tomak didn't develop and left and still didn't play, Karki ruined is career and was kicked off the U17 team, and Rowe decommitted. Scheel replaced Karki.
So, if these 3 worked out Tomek and Karki together in 2018-19 at the earliest, but most likely Karki would have come in 2019-20 with Rowe coming in 2020-21. These three not working out lead Berry to go to the portal a 4th time for a goalie. I wouldn't be surprised if going to the portal for a goalie continues.
