"What have you done for me lately" argument does not explain Kansas ranked that high. Without Embid they are not a top 10 team, possibly not even top 20. Pollsters can't assume that he will be back in the future if they are voting on "where the teams are right now at this point in time". I don't really care if Syracuse is ranked low with the loss the past week but that's just total homerism to have an 8 loss Kansas team with their best player possibly done for the season be that high for no reason.
I don't think I've ever seen an 8 loss team be in top 10 during regular season ever before. The only plausible scenario I can come up with for that to happen is for them to beat both a #1 and #2 team in last couple of weeks. Total joke. Also they beat Wichita State by 15 without Embid on a neutral court, but that's a different argument.
