Please don't take this the wrong way but I dont care about he stacks up against 2020 1st rounders in terms of WAR, Great that he is in tied 4th out of 30. Tied in 6th if you consider the entire draft (which I believe is much more appropriate). To me that only shows how much potential the guy has and how much it has been wasted. With his WAR/162 numbers he should actually be closer to 12. I do also prefer fWAR but thats honestly not an issue.
Most of the value he gets comes from baserunning and defense. With his injury history and the way just ageing works, he is in his prime production years and those numbers will start to nosedive in 3-4 years. So the injuries are key because he will never produce at the same level as he does right now and he won't have success in the long term (especially if his hitting degrades more)
