Print NBA MVP list in rust - sorting

Question

I was reading https://www.nba.com/history/awards/mvp.
And I tried to print out the name and count in descending order.
Kareem Abdul-Jabbar: 6
Bill Russell: 5
Michael Jordan: 5
LeBron James: 4
Wilt Chamberlain: 4
Magic Johnson: 3
...
As a beginner, I managed to do it like below.
I used a HashMap to count by name and a Vec to sort by value.
But I think there might be a better solution.
I will appreciate any advice to improve this.
use std::collections::HashMap;
const MVPS: &str = concat!(
"2017-18 James Harden, Houston Rockets (Voting)\n",
"2016-17 Russell Westbrook, Oklahoma City Thunder (Voting)\n",
... omitted for brevity
);
fn main() {
let lines: Vec<&str> = MVPS.split('\n')
.map(|line| &line[12..line.find(',').unwrap_or(line.len())])
.collect();
let mut mvp_map = HashMap::new();
for name in &lines {
mvp_map.insert(name, mvp_map.get(name).unwrap_or(&0) + 1);
}
let mut mvp_entry_list = Vec::new();
for entry in &mvp_map {
mvp_entry_list.push(entry);
}
mvp_entry_list.sort_by(|a, b| (b.1).cmp(a.1));
for e in &mvp_entry_list {
println!("{}: {}", e.0, e.1);
}
}

Answer 1

Finally I got better one.
use itertools::Itertools;
const MVPS: &str = concat!(
"2017-18 James Harden, Houston Rockets (Voting)\n",
"2016-17 Russell Westbrook, Oklahoma City Thunder (Voting)\n",
... omitted for brevity
);
fn main() {
let mvps_count = MVPS.lines()
.map(|line| &line[12..line.find(',').unwrap_or(line.len())])
.into_iter()
.sorted()
.group_by(|name| *name)
.into_iter()
.map(|(key, group)| (key, group.count()))
.sorted_by(|a, b| (b.1).cmp(&a.1))
.inspect(|(key, count)| println!("{}: {}", key, count))
.map(|(_key, count)| count)
.fold(0 as usize, |a, b| a + b);
println!("{}", MVPS.lines().count() == mvps_count);
}
