Eh, I wasn't talking 1 year rentals, despite the OP stating that. I was referring to rentals as a whole. Iowa had rentals at 133, 141, 157, and 165.
OS would have had four if VV had started the postseason at 149lbs.
FWIW, Cannon had two years when he came and the word is that he should be able to get a medical for this year - so he'll have two years remaining still.
As far as Penn State having rentals at 133, 165, 184, and 285 - I don't actually count Kerk as he transferred without ever wearing a tOSU singlet. Also they don't count either. It just isn't fair.
