IMO, they'll draft an OL if they believe he's the BPA. But I don't see them taking one just because it's the biggest need.
I don't try to evaluate individual players myself. Don't have the skills currently, nor the time to acquire them. But I do try to read as many different opinions (in non-Rams fans haunts) as possible about various suspects. At this point, there's been enough draft talk to start getting something of a sense of how the top suspects are shaking out.
And at this point, I'm a little skeptical about Scherff. Though he does seem to be the best OL in the eyes of most, it's not unanimous. I've seen at least one discussion where Andrus Peat was rated ahead of Scherff, and somewhere else I believe La'ell Collins was at least close to Scherff. In addition, he just doesn't seem to generate a lot of 'buzz' outside Rams' discussion forums. Unlike last year, when the whole world was talking about GRob and Matthews, this year there just doesn't seem to be a strong consensus about any OL being a sure fire top 10 pick, not even Scherff. Consensus seems pretty strong the OL is deep in general, but there just doesn't seem to be the outstanding suspects this year. This year, the 2 QB's and WR's seem to garner the LARGE majority of the 'buzz'. Don't even read a heckuva lot about the DT, Williams, even though the buzz I have seen suggests he might just be THE best player available.
Throw all the above in a pot of noodles, stir it up, and I'm starting to think the odds of a trade down from 10 might be a pretty likely possibility....unless they're high on one of the WR's and one falls to them.
The one suspect that I would most like to be a fly on the wall at Rams Park to hear discussion of is Mariotta. If he were to fall to them, would they take him.(??) I dunno. He doesn't seem to be the kind of QB Fisher would covet, but with Foles contract up after the 2015 season.......
