Isaiah just dropped 40 in a game not too long ago. I don't care what his ranking says, he is the real deal. He is one of the best players in the state.
Nobody I have seen dissed lalu and his shooting isn't bad, it's just not at the level that would be ideal for Painter's system and that is 40% from 3. He is a pass first player because he is on a team with a ton of talent. He just isn't a volume shooter. In his defense, not many are there shootingwise as incoming freshman. Also, Tyger gets steals, so his defense isn't terrible, but it will have to constantly improve. If Tyger buys in, he would see the court.
You don't piss away a scholarship on someone that won't play because you have it. If nobody fits the bill, Purdue is in a place they can pocket it. No glaring needs, but a wing and a guard will be needs soon enough. Swing for the fences, but unless you are dirty, you don't get in this late on top talent and win. Purdue isn't dirty and doesn't have glaring holes.
As for Herro, somebody committed that long generally doesn't jump unless there is some dirty pool going on. I'm guessing Duke or Clemson.
Side note:
It's so hard to reply to your comments because they are generally filled with absolute rubbish and/or you patting yourself on the back. I did my best, but I won't be doing it again on this subject.
