Should i drop Jon Lester?

The bottom of a pitching rotation is tricky because basically you are playing the hot pitcher at the right time. Contreras is a very streaky pitcher throughout his career but right now, he is on the good streak so it would not be smart to drop him. Litsch is a great young pitcher with good stuff and I wouldn't drop him just yet either. If I am dropping anyone from that staff, its definitely Lester because he has shown he is extremely inconsistent. He has pitched great games this year followed up by terrible game, and to me, unpredictability is not what you want on your staff.
