Yeah these are fair enough points. Bateman only managed about 73 MPH swing speed on today's home run, but that's plenty if you manage to find the barrel with an optimized swing path. I could see him hitting 10 home runs in a good year, but for Bateman I expect more of his power production would come in the form of a few extra doubles and triples over time vs launching balls over the fence. I think he possesses similar physical tools to Andres Gimenez as they are within a few ticks of each other in terms of average swing speed, and with Gimenez he did manage to smack 15 and 17 home runs at points of his career so it is possible to produce solid power output with lesser swing speed if you can unload on the baseball with your best swing and sufficiently find the barrel. In the early going Bateman has been showcasing an excellent hit tool which should allow for a high floor given his speed. I don't know if he necessarily "needs" to add a ton of swing speed to his game as he's been producing a ton offensive impact with the toolset he currently possesses, albeit with regression sure to come at some point.
