Passing a ball is a central aspect in the game of American Football. However, current passing machines do not fulfill the high quality standards for adequate catch training. ...
Additionally, a pass prediction model was developed to determine where the pass went to and which height to catch it by least squares fit of 225 sample points with a second order function (R2>0.99). ...
Acknowledgments: The authors are grateful to Jan Eisenbraun, the main pass receiver during the testing phase of the machine. ...

We address the problem of modeling and classifying American Football offense teams' plays in video, a challenging example of group activity analysis. ...
We define a football play as a unique combination of player trajectories. We develop a framework that uses player trajectories as inputs to MedLDA, a supervised topic model. ...
An offense consists of 11 players of which six play a critical role: quarterback (QB), running back (RB), wide receiver left (WR-L), wide receiver right (WR-R), tight end left (TE-L) and tight end right ...

In American football, only discrete-time estimates of play value were possible, since the most advanced public football datasets were recorded at the play-by-play level. ...
In this work, we make two main contributions: First, we introduce a general framework for continuous-time within-play valuation in the National Football League using player-tracking data. ...
Framework for Continuous-Time Modeling in American Football As the first step towards building a continuous-time valuation framework for American football, we model the expected end-of-play yard line. ...

Analysis of player tracking data for American football is in its infancy, since the National Football League (NFL) released its Next Gen Stats tracking data publicly for the first time in December 2018 ...
While tracking datasets in other sports often contain detailed annotations of on-field events, annotations in the NFL's tracking data are limited. ...
Importantly, this does not mean that the patterns of motion of defensive backs in man coverage will follow well-defined trajectories, as is the case for wide receivers. ...
