Not sure Purdue doubles TJD, when you get a dude like Edey waiting, BUT.....coming from the weak side to help is a much easier way to pick up a cheap foul----especially if you are late.I agree you don't double Edey just switch up defenders. If I was Purdue I'd definitely double TJD.
Look for IU(HOPEFULLY) to put Edey in some PNR, ball action situations. Make him defend away from the basket. ALSO, it pulls him away---opens up possible offensive boards, or allows Renau/Race to work one on one..
If I'm Mike-----I run, run and run...
