Who do you suggest? Other than Vlad Jr and Bichette, both whom do not seem like leaders due to their age and (for me) their down seasons, I've only been able to come up with one solid name: Christian Walker. And I am not even sure if he will be available. He's a pending free agent, but his availability will depend on whether the DBacks GM likes their chances and how they perform over the next month. Right now they are only 1.5 games back from the wild card.IMO the right vet with the right attitude could wake up most of this lineup. They lack a leader with a killer instinct.
You don't have to change half the lineup to impact the clubhouse culture. One or two is more than enough.
They won't go after them either way, but that's all it would take.
