To score a ten would be just fine but I'd rather be dressed to the nines

Looking at pictures from the Bard scrimmage two ideas present themselves. Firstly, teams with weak marks, even one weak marker, are easy to beat on offense. Emphasizing team-wide tight mark defense for the rest of the semester will pay dividends.
Second, if you are close to the end zone line or another position when a short throw is the only option, if you don't have an easy to execute low release throw its probably a good idea to swing the disc. That's more of a personal issue, I don't swing it to the other handlers enough.

Also more often than not, a hammer should not be used as a high count bailout close to the endzone. That's something a lot of people find counterintuitive - since a hammer is nearly impossible to block and flies over the defenders, it is often used to get out of a tight spot at a high stall count. But at that point, if the swing is not open, either a flat low release throw under or through the defense, or a high flat throw are better.

Why? A hammer is a precision throw. If you put it up and the receiver is out of position, they have a very small margin for error. Meanwhile, a flat throw will float and give the receiver a chance to make up lost ground if they make a bad play or the throw itself is off target. In a high stall count situation the throw is more likely to be rushed, so a throw that provides a greater margin for error is a better choice.

The above is a direct result of looking at pictures of the blading hammer I threw to Tom. While it was on target, it made for a challenging reception and looking at the pictures I could have gone low release.

Why ever not go low release on the short throw?
