How do I wrap this script in a pcall? Do I need to add any other things to make it work better?

--Leaderstats script for new flight simulator

local DatastoreService = game:GetService("DataStoreService"):GetDataStore("FlightwareDSS")

game.Players.PlayerAdded:Connect(function(player)
    local leaderstats = Instance.new("Folder",player)
    leaderstats.Name = "leaderstats"

    local GROUPRANK = Instance.new("StringValue",leaderstats)
    GROUPRANK.Name = "Rank"
    GROUPRANK.Value = player:GetRoleInGroup(8323568)

    local MINUTESFLIED = Instance.new("IntValue", leaderstats)
    MINUTESFLIED.Name = "Minutes Flown"
    MINUTESFLIED.Value = DatastoreService:GetAsync(player.UserId) or 0

end)

game.Players.PlayerRemoving:Connect(function(player)
    DatastoreService:SetAsync(player.UserId, player.leaderstats["Minutes Flown"].Value)
end)

I have heard that wrapping this in a pcall is a good idea. How do I do that? Is there anything else I should consider adding? Is there a way to autosave incase the player gets kicked. I ask because apparently when the server shuts down, the PlayerRemoving function doesn't occur.
