Yes, Bagley has much more potential as a go-to scorer and is a much better rebounder. I did not mean that Jackson is better than him in every way, but as far as pairing with a larger variety of big men, yes, you can put almost any type of big man next to Jackson with the exception of a weak rebounder (where he does need help).
JV paired with Bagley would only clog up the inside. Bagley was looking decent from 3 when he caught the ball wide open with his feet set. Jackson was creating 3's on step-backs, it's fine to put him out there while Jonas plays inside. With Bagley, it would be dumb to have him camp out at the line with much regularity considering his strength scoring in the post. There were only a handful of guys available, Dedmon being one of them, who could open up the floor for Bagley and also be a shotblocking threat. Luckily, we got one and Bagley's game should flourish as a result.
