They're all looking to drum up distraction stories at this time of the year. I'm sure this "journalist" went in to the Q&A session knowing full well what his intent was - to get quotes for an article meant to drum up speculation (and clicks) on the current mental state of players as they are going into the NCAAT. And it just so happens that Kentucky is more susceptible to speculation given the massive annual turnover in players and recruits.
With that said, all one has to do is look at Cal's years at UK and his track record with transfers. How many have there been? I can only recall these to have left under Cal's watch:
Marcus Lee
Kyle Wiltjer
Darnell Dodson (left the year Cal was coming in?)
Stacey Poole
Ryan Harrow
Charles Matthews
In contrast, Tubby had WAY more transfers out of the program than probably any coach in UK history (including four in one year, TWICE!):
Myron Anthony (98-99)
Desmon Allison (99-00)
Michael Bradley (99-00)
Ryan Hogan (99-00)
Nate Knight (99-00)
Jason Parker (00-01)
Rashaad Carruth (01-02)
Adam Chiles (01-02)
Cory Sears (01-02)
Marvin Stone (01-02)
Bernard Cote (03-04)
Shagari Alleyne (05-06)
Rekalin Sims (05-06)
Adam Williams (05-06)
And of course good ole BCG who had two straight years of 4 transfers each:
Mark Coury (07-08)
Derrick Jasper (07-08)
Alex Legion (07-08)
Morakinyo Williams (07-08)
Kevin Galloway (08-09)
Mark Halsell (08-09)
Landon Slone (08-09)
AJ Steward (08-09)
So obviously Calipari has done better with keeping players around, even in light of having so many of them being recruited over. So this is why we should take caution in articles like this that are meant to drive speculation and "worry", and look at history. Hump would be a fool to leave - just ask Josh Harrelson.
