If you're basing USC's style of play on this one game, you haven't seen a lot of USC play this year or since KM took over the program. When Ali was the coach, watching USC play was brutal. In fact I would say the style of play was brutal. It was very direct and much more physical. They were slide tackling all over the place while picking up penalties and yellow cards. Since KM took over the program, USC has evolved into a more possession team and it is much more enjoyable to watch. My daughter and I attended six games this year and possession was always the order the day. Playing over the top time of possession was in USC's favor for all, but the UCLA game.
The WVU game was an anomaly this season because of the relentless attacking style WVU chose to play. They kept a high line which put pressure on USC and made it difficult to play out of the back. It also made them susceptible to the counter attack which is why he started Taylor McMorrow. She only started 3 games all season. He scouted this team well and was looking to put pace up top to hold WVU's as far back as possible. Eventually, USC was able to finally break through with a couple of counters.
I've watched a lot of USC soccer over the years and after the dark days of Ali Khosroshahin, watching the Trojans under Keidane McAlpine is refreshing. I will say watch Alex Anthony was really frustrating for my daughter. She can score goals, but she gives up way too many balls.
