People trying to compare Rousseau and Phillips are being premature. Phillips has clearly progressed this year, looks much better now than earlier in the season. So we're seeing a more polished product. Meanwhile, Rousseau only had half a season as a Redshirted Freshmen. He's been conditioning with a specialized group to prepare him for the draft. I'm quite certain he's rusty on the field but will crush the combine. So they're just moving along two totally different tracts in development.
Personally, I don't see Phillips getting a look in the first round because of his injury and slow return to form. Maybe late second, probably third. I think he should come back. He could be high first if he has several Duke-like games next season, which he will.
