Yes, the Memphis case is exactly the same,
except for the fact that Memphis was aware of the allegations concerning Rose’s SAT score in October of 2007, investigated the matter, and chose to play him during the 2007-08 season anyway; the fact that the NCAA concluded that Memphis obtained a “competitive advantage” by playing Rose (obviously), whereas Davis was a walk-on special teams player who played in 6 games, recorded a grand total of 6 tackles, and made no difference in the outcome of any game; the fact that Rose, after twice failing to get a qualifying score on the ACT in Chicago (where he lived), “took” the SAT in Detroit, but a handwriting examiner concluded that it was not his handwriting; and the fact that Memphis also provided impermissible benefits to Rose’s brother, which the NCAA concluded would have rendered Rose ineligible even without the SAT fraud. (Google NCAA public infractions report Memphis.)
With all of that said, if you think the NCAA is going to treat a high profile player such as Derrick Rose, playing under a high profile repeat offender coach such as Calipari, the same as a walk-on player who we didn't even recruit, well . . . ok then.
