I don't think they keep 7 WR's on active roster. One of those drafted will be on the PS to start the year IMO. Who knows though. How many did they start with last year on the active?
I will admit I am biased. I watched every UCF game this year, but I would be shocked if he doesn't get drafted. Wouldn't surprise me to see Seattle take him as they already have his brother and seeing Pete C.'s reaction to him at the combine.
