The way Kansas has played so far, no game (or lead, for that matter) is safe. Still, some games are tougher than others. I looked through the remaining schedule to see which games ahead are likely the biggest obstacles, and ranked the top ten (note: this list excludes the Kentucky game, because I wanted to focus on Big 12 games and the SEC challenge will mean very little at the end of the season).
10) Home vs K-State on 2/25
As you can see, the bottom of this list won't exactly look terrifying. This made the cut over the three games not listed because KSU plays great defense, and Kansas has been prone to playing.
