Hummm, I doubt it, but let's break it down.
You have to keep: Miguel Cabera, Vernon Wells, and Hideki Matsui...dang you have a lot of young talent. Ok, these are your only no-doubt keppers who aren't rookies.
I'd keep: Because they should all be going to be big contributors in 2007, I like Stephen Drew (over Tulowitzki), Delmon Young, Jeremy Hermida, and Justin Verlander.
Shoot, that gives you five OF...is that too many?
You need to make some trades. You have so much great keeper talent. No only are your young players good, but they're exciting, too.
So, unless you make some major trades, or for whatever reason you like Tulo a lot more than Drew, I don't see room on your roster for Troy Tulowitzki.
