You define playing style as who he throws the ball to. His #1 target graduated, so he will have to work with other players. Making such an obvious statement does not mean he will have to "change his style".
It seems to bother you that we are not all wringing our hands over the loss of Edey. Your statement that "it seems Purdue fans are really dismissing how good(and large) Edey was" is just silly. You guys were borderline respectable (FINALLY!) TJD's senior year, and when he left, you returned to sucking. He was one of IU's all-time great players. You don't understand why we aren't worried the same will happen without Edey. Purdue was good before Edey (didn't suck), and they will be good after (won't suck).
I remember when Purdue lost Russel Cross to the NBA after his junior year. The conventional wisdom was, without their most dominant player, Purdue would finish in the lower half of the B10. When Glenn Robinson (like Edey, one of the greatest players of all time) left for the NBA, people said the same thing. If you had been around during those times, you would have been saying the same thing you are saying now. But both times, Purdue came back and won the B10. I won't predict that the same will happen after Edey, but I won't be surprised if it does. Purdue will be fine. But thanks for all of your concern for us.
