This is the problem with retaining a coach who clearly sucks.
Even someone as delusional as Grifol recognizes that he’s on the hot seat. He's in survival mode. His decisions are going to be based on what he deems best in the short-term, because that's all he's guaranteed to be here for.
Finding out what we have in Colas, Sosa, Lee, etc. and being patient through their growing pains is what's best long-term (heck, probably short-term as well), but Pedro likely sees it as a one-way ticket out of town.
