Jordan Spieth has become the latest PGA Tour star to offer his thoughts on Jon Rahm's future amid reports of a $300m LIV Golf switch.
Further speculation has been fuelled by the fact the Spanish World No. 3 has been curiously silent on social media in recent weeks.
According to some reports, Rahm could be announced as the latest LIV Golf signing as soon as next week.
It is said his deal would be worth approximately $300m over six years.
Spieth has joined the PGA Tour's policy board after the aforementioned McIlroy, 34, resigned from the role.
The three-times major champion wouldn't be drawn into speculating about Rahm's future, but he did say the 2023 Masters champion is one of the Tour's biggest assets.
"So it would be a really -- really not very good for us [if Rahm left] in general because we want to play against the best players in the world and that's what Jon is," Spieth said.
"I know there's been some guys that have talked to him. I know he's maybe weighing some decisions, maybe not. I really don't know, so I don't want to insult him and say he's weighing decisions if he already knows he's not or he is.
"You know, that's somewhat out of my control in a way. Obviously I could speak probably on behalf of 200-plus PGA Tour players in saying that we really hope that he's continuing with us."
Asked by one reporter what Spieth would say to convince Rahm to stay, he said: "Again, like what's weird is if he's not considering it at all, which I really don't know, then it would be an insult to be just playing this game with him to even answer these questions. He might be insulted by it."
He continued: "You know, I think for me, if it were me, and I don't even know if I ever got an offer, but I like the way that I play four rounds of stroke play the same way we play the majors.
"I believe that we're playing against the best players in the world, and it's what I've always wanted to do is to play out here and try and catch PGA Tour wins, catch the legends of the game. It's a history thing and the money's a bonus."
