You're crazy because...
I think the front office has already stated they intend on starting him at AAA to start the year, so it's a moot point. Other than that, I dunno about all the stats you quoted, but I disagree with one for sure - a .303 OBP is terrible. Add an incredibly high strike out rate to that and you've got a lineup killer.
On the other hand, I think I understand where you're coming from - if we're just going to be bad anyway, why not let him learn at the ML level. I'm still hopeful the Cubs will make a few moves this offseason and be competitive. Time will tell, my friend!
The front office says alot of things.
Still, I don't think that this team has to reserve itself to being bad in 2013. A Jackson/Sappelt platoon could be very productive. Jackson should be the one to win or lose the job out of Spring training. He's not a raw 19 year old. He's 24, and looking more and more like he is what he is. If he's really struggling after the first month or so, send him to Iowa.
