I don't have a problem with a lot of the names mentioned above if they want the job. The tricky part is the fact that USC plays in Conference USA and it's hard to recruit "SEC" type of athletes to that. Clemson should always have us beat in men's soccer because they can say, look at our conference and who you get to play. Their is NOTHING attractive for a high quality athlete to play against in C-USA, so you're basically getting mid-major talent (unless it's a kid who just always wanted to go to USC). To me, that's the biggest thing that will hinder anyone with men's soccer.
As for Berson. It's definitely time for a change. It's gotta be hard to fire a legend, and I get the feeling this was a "Look, you need to retire so we don't have to fire you" and the additional year was out of respect to him. I don't have a problem with that.
As for Tanner's ability to hire. I think you have to look at what he's done objectively:
1. Baseball: hired Holbrook - absolutely the right hire AT THE TIME he was hired. It didn't work out, so he's gone. Kingston is another one who looks like a good hire based on his ability to win at programs without a lot of resources and college baseball writers and insiders seemed to think it was a good hire. Again, a good hire at the time. We'll see if it works out. He needs a little time though as baseball IMO is the hardest to turn around quickly due to scholarship limits that levels the playing field so mid-majors can compete for quality kids with the Power 5.
2. Muschamp: Mediocre hire that seemed to pay off early with 3 straight bowls and a 9 win season, but this year was a huge disappointment. Other than taking a risk on a coordinator, I don't know that we were going to land anyone better among the list of "hot coaches" that year: Tom Herman was never coming here and Kirby Smart had offer in hand and UGA fired Richt, so it made sense for him to go there.I think anything less than 7 regular season wins next year and Ray will have to pull the trigger.
3. Volleyball coach: Great hire here. Team hadn't been to NCAA in more than a decade, and this new guy brings them to NCAAs in each of his first 2 seasons.
