The technique that this sentence best illustrates is understatement.
Understatement means that you are not showing the full 'strength' of something, but it is rather understated - so here, the coach only said that 'he was glad' even though his team won the Super Bowl, which is a huge deal. So his emotions should have been way stronger.
Thanks luv this really helps it says it’s incorrect
Narritive writing <span>relates a clear sequence of events that occurs over time. Both what happens and the order in which the events occur are communicated to the reader. Effective </span>narration<span> requires a </span>writer<span> to give a clear sequence of events (fictional or non-fictional) and to provide elaboration. Hope that helped you :))</span>
