I read that Lozano article on Deadspin again, and this paragraph is quite interesting:
"He'd do this one thing all the time," a former co-worker recalls. "Say he'd get an offer of a million. He'd go back to his player and tell him they'd been offered $800,000, but that was way too low and he'd do what he can. He'd wait a few days, accept the original offer, then tell his player: ‘I talked them up to a million. See how I fight for you? See how I fight for you?'
