Tyee Robinson: often beaten, not a sure tackler. Oliver was a question mark, didn't start much: didn't impress when he did. Juwaan Williams has the skills but has spent most of his career injured so he's an unknown, too.
Schooler: started as a freshman, made many open field tackles, ferocious ball hawk. Put him on offense where he has no experience at this level; start in front of Ofodile and Lavette ?
If Schooler can pick up complex routes so quickly (in fall camp, for crimey's sake?) what does that say about guys who've spent years as WRs and can't crack the rotation? Malik Lovette is a real surprise, not a good one: rated one of the top athletes in the country, he couldn't make it on O, then went to D, now he's back on O. Strange. 
The true freshmen WRs are intriguing and were highly successful in high school... but the Ducks have been burned worse at this position than any other in recruiting in the not-too-distant-past: a host of 3-4 stars (one or two 5s) never started and left...
