Also, batting average is a bad stat and not a good indicator of anything. OBP is a much better stat, particularly for a lead off guy who is going to not typically be a power guy anyway. A walk is every bit as good as a single.
Coleman's OBP with this rookie season was .320 (which was about league average for the time) and dipped down to .301 his second season (way below league average). You can argue that it still made sense to lead off with Coleman over, say, Tom Herr (OBP .379 in 1985) or Ozzie Smith (OBP .355 in 1985), because of the Coleman's insane # of steals (110!). But I also think people's perceptions of what contributed to winning baseball was just very different back then. For example Coleman made two All-Star games. One in 1988 when he had a bWAR of 0.8, then the following year when he had a bWAR of 1.7. Back then speed was considerations no. 1, 2 and 3 for a leadoff hitter. Nowadays you can have a guy like Kyle Schwarber have more career ABs in the leadoff spot than anywhere else in the order.
To get back to Scott his last season was .305. League average in 2025 was .315. So Scott was below average in getting on base, and he had a worse OBP than Herrera (.373), Donovan (.353), Contreras (.344), Burleson (.343), Nootbaar (.325), and Winn (.310).
I get that he's young and we're not really in it to win anything in 2026 anyway, so the idea is to give him a shot and see if he develops there. But at the same time batting leadoff can also pile on pressure that he's not having at the bottom of the order.
