Have a receiver facing you about 10-15 yards away. Throw blady OI scoobers aiming to hit the right shoulder and IO's aiming for the left shoulder. Once you can do that, go back to normal scoobers that end up pretty much flat (i.e. the print is facing straight down). I can think of three situations where a scoober is the right throw:
- Popping a scoober over the cup to someone who is standing still.
- In endzone offense, if you're forced backhand and you're looking for an iso at the front of the stack. It's a thrower-led pass to space on the break side. The throw is flat to slightly inside out.
- You're trapped on the sideline with a backhand force. Your dump cuts upline and has lots of space in front of him. If his defender goes hard inside to try to cut off the angle for the backhand, you can pop a scoober over the top that will sit in front of the dump cutter.
Do the same, aiming to hit the appropriate shoulder with a blady IO or an IO for distances of 15-40 yards. After that, throw to a cutter who is making horizontal cuts each way, angled cuts, or cuts directly away from you. For the away cuts, you want the throw to drop in over the appropriate shoulder and sit in front of the receiver. Also, check out the discussion here.
By blades, I just mean an OI forehand that doesn't sit. Again, you want to start off aiming at the left shoulder of a stationary receiver. If you can control your blades, they are a great weapon for baby hucks of 20-40 yards. You can often place the disc where your receiver can get to it but his defender will never have a chance.
