Is it me or is Junior Dos Santos vs Roy Nelson Main event level?

Maybe its just me but i really wanna see this fight if this was the only fight on the card i will still pay to watch it...no a lot but still...and its not even co-main event its the first fight on the main event show....the main reason i wanna see it is to see if Roy can really be considered top 1 or 3 cl but i juts don't see him getting past Dos Santos i think Junior will put him down and early..but maybe if Roy can get him down before that...we can see the under dog take it home all an all i don't see this one going all the way...it could be Dos Santos via TKO or KO in round one or two or Roy Nelson via submission or TKO (from crucifix) in round Two or Three what do you think ?
