Early games for us the criticisms of Ohio were poor first touch and poor positional awareness.
His goal against Ipswich 2 months later showed that he's thinking much more as the game unfolds. The cross from the freekick goes to the back post, way over his head, he doesn't follow it, he drops back anticipating the knock back. Meanwhile his marker and the other defenders have moved towards the goal line leaving him with plenty of space when the ball comes back over.
His technique to finish was good; although it went in off the underside of the crossbar.
If he'd have put it over the bar people would be berating his poor finishing. It's really fine margins.
He definitely improved with us. Whether that's enough for a contract, possibly not.
Even putting his goals aside (as you say, there's such fine margins with goals and people put too much stock in rating a player based on them) his general play, movement and positioning as you've highlighted were far better. He held the ball up well against Cov, and think there was an instance against Ipswich where he lost possession but followed up with a second effort and won the ball back. Miles better than he had been up to the Stoke game.
