The Blues are fairly deep in forwards at the NHL level, coming off their Stanley Cup triumph, but could use more organizational center depth. Therefore, adding Joshua here makes sense. He will likely play in the AHL for San Antonio in '19-20 and is considered a marginal prospect.

The Maple Leafs were going to lose Joshua's rights on August 15 had they not signed him by then, and it had become clear that they were not. So, they moved him to an organization that was willing to sign him in St. Louis and got back futures--which may not amount to much at all.

Joshua has not fantasy value at this time. He must first prove himself in the pro ranks and then slowly climb the prospects list for St. Louis.
