Of course you can and you should.
Conventional wisdom says you shouldn’t bother. But arguing with failure is dumb. Failure doesn’t need to be argued with, it’s already failed.
It takes guts to argue with success, guts and insight. And it’s the best way to make things better. It is better to change a winning combination.
Old rule: Don’t change a winning combination;
New rule: Safe is no longer safe, change and improve a winning combination.
The 2010 FIFA World Cup defending champions, Spain were eliminated from the 2014 Brazil FIFA World Cup in the first round with humiliating scores. They kept the same winning squad in 2010, same technical staff in 2010, a winning combination that was no longer a winning combination.
