How to detect a player's previous team?

I'm making a pixel art game where you can disable other players from coming to where you draw. What I'm trying to do is detect a player's previous team, so that I can make their bridge able to collide again if they have no teammates. Here's a bit of my script:

			print(player.Name.. " has joined " ..team.Name)
			local resetBridge = true
			for _,rPlr in pairs(game.Players:GetChildren()) do
				if rPlr.TeamColor == plr.TeamColor and rPlr.Name ~= plr.Name then
					print("has teammates")
					resetBridge = false
				end
			end
			if resetBridge == true then
				print("reset bridge")
				local path = workspace.Paths:FindFirstChild(tostring(plr.Team))
				if path then
					print("found path")
					path.Transparency = 0
					path.CanCollide = true
				end
			end

It prints when a player joins a team, but the problem is that it only picks up the new team when it tries to make the path able to collide.

You will need to store it inside of a table.

local Teams = {}
local Player = game.Players.LocalPlayer
Player:GetPropertyChangedSignal("Team"):Connect(function()
table.insert(Teams, Player.Team)
print(Player.Name.." changed team to "..Player.Team)
end)
