There's no point having Suarez in the pen if you aren't going to use him. And down 2 runs late is perfectly reasonable.
Suarez is just unable to produce. So he's probably gonna get the boot.
I think the whole "trust your stuff" mantra is mostly bullshit.
I think the issue isn't a lack of confidence in stuff, but a flat out inability to throw the ball in the strike zone at will. I'm sure he's trying to throw strikes, he just can't.
