"Within four games under the management of a new coach, team
performance improved. However, further analyses revealed that this increase was
due to regression to the mean and cannot be attributed to the new coach. A control
group comprising teams that had an equal performance dip but did not dismiss their
coach showed a similar improvement. We conclude that coach turnover in Belgian
soccer is neither an effective nor efficient means to improve performance in the short
term."

“We find that, after the head‐coach has been replaced, teams perform better than before. However, the performance is also better than before for a control group of coach replacements that did not occur. From this we conclude that replacement of head‐coaches does not improve team performance”

“After controlling for a mean‐reversion effect, teams that changed their coach within‐season are found to perform worse subsequently than those that did not, but the negative effect is short‐lived.”

Gräver som sagt gärna fram mer exempel från alla möjliga sporter och ligor, inte minst hockey.
Slutsatsen är att det är ett dåligt beslut att sparka en tränare under säsong och således inget som LHC borde syssla med framöver.
