Yeah, there's no need to keep YS2 around. Even if one of the two stadiums had an unexpected delay, the other new stadium would remain an option. The Yankees could play at Citi or the Mets could play at YS3. And believe me, they'll get it done. Even if some of the restaurants aren't completed, or if there are fewer working restrooms than they wanted, or anything like that, they'll open anyway. As long as there are seats and electricity and fire alarms and whatever else is needed for an occupancy permit, the ballparks will open. And those are the things they'll make sure they have done in time.
