That only works if the player is only shooting 1 FT. Players shoot 2 on shooting fouls more often than not. 40% FG% = 40% FT% most of the time (on 2s, 60% for 3s).
Foul drawing is a crazy valuable offensive skill (Harden level baiting sucks to watch though).
I want to keep talking about Dejounte Murray:
The synopsis is that considering the entire context, I think Murray should be a target. He complements what the Jazz are going to have, checks off so many boxes that so few others can, and is almost certainly going to be available in the next two seasons. Without warts, Murray becomes increasingly unattainable. Lastly, foul-hunting is often a NEGATIVE attribute, especially in the playoffs or in the clutch when officials generally swallow their whistles much more.
There is huge value in drawing fouls, but it is one aspect to the game. Like almost every other attribute, it exists within a context. The context with the Jazz is that moving forward, there is an emerging weakness at the guard and wing spots positionally, and particularly with the attributes of shot-creation and setting the table for others. Ideally, you have good size in the backcourt and players that can be effective with the ball but don't need to dominate the ball to be effective, which retains or perhaps creates the possibility of "position-less basketball" and still checking off the checkboxes across the team so it's not just a blob of homogenous players without any particular strengths.
The Jazz have a base of Lauri and Kessler to work with. What they both do is score in an insanely efficient manner. WK lacks volume, but has an elite FG% while Lauri is arguably the most efficient volume scorer in the NBA. What neither of them do well is create shots or "play-make". What both of them benefit from in an outsize manner is getting their tables set. I've already mentioned that I think Murray generally makes up for his lack of drawing fouls by checking off so many other boxes elsewise, but in the Jazz's context, the lack of foul-drawing is further buoyed by the outsize benefits he would provide this team and that Lauri and WK offset that weakness further by providing an efficient scoring base. And given Murray's size and skillset, you either end up with a huge, switchable backcourt, or you get a second guard to help reinforce whatever creation your lead guard is generating.
The Jazz are in a position to take some calculated risks regarding their salary situation for the next four years because of their pristine cap sheet, their likely-influx of rookie-scale players filling out the roster, and that any substantial raises for any of those rookie-scale guys won't happen until 2026 at the earliest (and this should honestly only apply to Kessler).
Regarding the point that Murray is a salty SOB: salt is a spice. Too much of it is poison to the point of killing even land. But some of it is necessary for basically any biological function or for anything to taste good. Right now, the Jazz are a 100% sugary culture/situation and I think they could not only afford to take a pinch of salt, they might even benefit from it.
Lastly and as it pertains to the thread itself: Murray is almost exactly the archetype of player that a weird fit like Donovan needs to succeed at a high level. It would be wise to stock up on players that play at a high level and fit any situation and Murray is basically that. If the Jazz are replete with high-level players that facilitate fit as much or more than require fit around them, they can afford to take a calculated gamble on a player less complete but with superstar scoring ability at some point down the road.
