I first read it as 11 of our 12 total signees are from state of Purdue.
It now makes a little more sense if it means 11 of the 12 targeted players from the state of Purdue ended up signing.
However, the more states that are considered constituents of "state of Purdue", the more likely the 12 is a mistake.
Even if "state of Purdue" was just a weird way of saying Indiana, would this be an impressive stat? Because given the quality of talent in this class, I would say if that if they got 11 of the 12 they targeted, perhaps they set the bar too low and need to target better players.
It's obviously a confusing statement, and I'm pretty sure it's a meaningless one as well.
