Coach Joerger after the Clippers game ”I am going to play him at point guard. So, there will be times where it is going to be him and Buddy, and there will be times where he plays with De’Aaron, and there will be times when Buddy plays with De’Aaron. So, kind of spin those guys around a little bit"
Also played some point against Indiana on Saturday, where he had 6 assists.

Here's why:

1) Precedent: Isaac played nearly a third of his minutes at the 3 last season: 27% at SF; 73% at PF.
(https://basketballmonster.com/usagemonster.aspx). It’s worth noting that these percentages came in a season of Aaron Gordon playing only 58 games, which inflated Isaac’s time at the PF whenever Gordon was out. As you can see in the graph, Aaron Gordon played a whopping 98% of his minutes at PF, which anchors this claim to Isaac as a SF.

2) Internal confirmation: According to Magic official team reporter John Denton, Jonathan Isaac “will resemble a small forward on offense and a power forward defensively’ this season.” I’m not entirely sure what that means, but the official team reporter acknowledges Isaac as a SF...at least half the time, haha.

3) 18-19 Starters: Josh Loyd of Locked On (among other sources) have projected that Orlando’s starters for this season will be Augustin, Fournier, Isaac, Gordon, and Vucevic. This is the lineup Steve Clifford rolled out in the Magic’s first preseason game against the Sixers (https://twitter.com/Magic_PR/status/1046875117811372033). This lineup necessitates that the slimmer Issac slide to the 3 while Gordon mans his natural position at the 4.

4) “Everyone else is doing it.” This isn’t an ironclad argument on its own, but it’s worth nothing that Jonathan Isaac is SF eligible on the fantasy basketball servers of ESPN, CBS, FleaFlicker, and Basketball Monster. FanTrax and Yahoo are the lone holdouts. You don’t want to be the last ones to join the cool kids’ table, right? :)

I understand that Yahoo has a system for updating player eligibility in Fantasy Basketball, but I would like to suggest a small change that would likely help all managers across Yahoo Fantasy Basketball:

A player that misses 3 games OR a week of action--whichever comes first--will become eligible for the IL roster spot. Considering that a player may (typically) play anywhere from 2 to 5 games in a given week, it should follow that a player should be IL-eligible based on either games missed OR time missed (again, whichever comes first).

Yahoo currently only changes a player's status to IL-eligible after they've missed a week OR are projected to miss at least a week. This is problematic because it doesn't account for enough of the situations that are causing managers to be without key players (as is evidenced by the number of comments already posted on these Forum pages).
