In american english, when referring to a sports team, people often refer to their favorite team with terms like we, us, or our. Even if the person speaking is not a member of the team but just a fan. Someone would definitely understand your sentence, but a native american english speaker might say something more like. "I wonder how our first 2 games will go this season." If they are talking to another fan of the same team or if your favorite team is obvious from past context.

It sounds fine.

(Australian English) If telling someone: "I dunno how the first 2 matches will go this season." ("dunno" = "do not know") If asking someone: "Howdaya reckon the first 2 matches will go this season?" ("howdaya" = "how do you") ("reckon" = informal "think"/"believe")
