This has been pointed out before: He's obviously fiddling with his secondary stuff. IIf you've watched his outings, you'll notice he's not throwing the heat as often as he did in years past, yet he's still getting a bunch of groundball outs and keeping his velocity into the end of his outings.
The whole mechanical analysis i take with a grain of salt because people here are watching him pitch on TV, and we're fans anyways, not pitching coaches. Not to say i don't agree he's flying open, and he's a bit inconsistent, but it's impossible to go as in-depth into his mechanics as some people here are trying to do without first-hand observation. It's just not the same on the TV.
As for the rest of the point, my problem is with the proclamation by some people that "they always knew he wasn't a starter" when that sentiment wasn't presented until a couple days ago. And also, less than 15 IP this Spring. Sometimes people have their finger firmly on top of the panic button at all times and want to create a storyline out of nothing.
