Hmm. That doesn’t look like he slid off during taxi, looks like he just slid off the end, turning it right at the last second. Midway doesn’t have very long runways, but they’re (mostly) plenty long for a 737-700 like that.

Ran off the runway?
Looks like the pilot went mudding. Ooops, forgot to lock the front hubs.
Looks like the pilot turned at the end of the runway to go into the grass instead of the crushable material used to slow down runaway aircraft. He must not have been going very fast at this point, or he would have just taken the straight line into the crash barrier. Probably saved a lot of money in damage to the aircraft and the runway by making that turn.
