I would also say his anticipation/range seems to have improved a bit this year. I'm not convinced he's "above average", but even playing close to average defense is a meaningful improvement.
His sprint speed is similar to past years, except that one year where he showed up plump as f***. I just think he's not running into as many outs as last year. His 26.8 sprint speed is 37th percentile, he just needs to make less mind-numbingly poor decisions to dramatically improve.
