I agree with you to a degree, Kilo. He will improve as he gets accustomed to all the changes. That said, the biggest improvement will come if he's able to master the strikezone, something he lacked early, middle, and late in the season, so I'm hesitiant to attribute that to fatigue only. If what we've seen thus far is typical of his command, he'll continue to make his own mess and get burned by it. Consider me very cautiously optimistic.
