That's my point, Knowname. My comments are not solely about two bad outings out of four. It's the TJ surgery, his age, his poor spring, etc. One could argue here, similar to what you wrote about Frankie, that Nathan is just not the same since his surgery.
But, the pro-Nathan crowd wants to simply disregard everything else and say, "Hey, he blew two saves, big deal." Well, if it were just that, and nothing more, I'd agree. Unfortunately, it's a combination of several things (see above), not just two bad outings. To see it otherwise is to put on rose colored glasses and not see the elephant sitting on the table.
Now, could things change? Sure. But, the question is, how long do you wait? I am not ready to give up yet, but I can tell you that my string is getting short.
