I think the entire pitching coach staff should be changed. Its not just the young guys its everyone thats struggling. They clearly don't have a solid game plan when going at teams.
An example of many: The last start Jon Lester had he was supposed to throw fastballs to start and get ahead then use his breaking stuff after. He has his best control with the fastball and before anyone says Javy Lopez can't call a decent game....it was the coaches that were calling the game. Suddenly after the 1st inning (which went well) he started off with breaking pitches and got crushed. Why did they make the change and put Lester in that situation?
Also, why can't they help Josh Beckett on a game plan where clearly he throws too many fastballs and has no idea how to attack certain hitters. Rudy Seanez, Julian Tavarez, Manny Delcarmen, Craig Hansen, Mike Timlin, Keith Foulke, Beckett, Lester.......EVERYONE sucks. Even if its not necessarily the coaches they should be changed to create a new atmosphere because the current one is terrifying and shows no signs of improvement.
