Cubs - A season of failure

So as I sit here and type I am watching the Cubs and Marlins. As per usual the Cubs are losing to the lowly Marlins. Greg Maddux, a bright spot in the early season winning 5 of his first 5 starts hasn't won since. He has just given up 5 runs in the 5th, allowing the Marlins hit for cycle with 2 outs. This just should not happen. It is a disappointment. I am bit frustrated with it all. When I am in a better mood I may comment more on this later. A team with this much potential should not be this bad. Why Cubs do you do this to me every year?
