I just don't think you can pass on a top CB at 19. Because honestly.....right today.... we don't have any starting CBs. Akehelo is a FA.... neither Kendricks or Durant have stood out as being a guy who's a concrete starter.... So yeah, either way.....if bring back Witherspoon, or sign another FA...you still need a CB...and if you get one at #19, than you have at least 1 starter.
We already have a starting Edge...so whoever you draft there is competing with Hampton, Mathis, Thomas, and a FA (Hoecht or another free agent). But either way you go, you still have a solid starter in Young.... and to me.... Hampton, Mathis and Thomas are better at Edge than Durant and Kendricks are at CB.
So we need a CB ..and we can get a really good one at #19. Quinyon Mitchell is looking like a solid player in the 1st round, and we could possibly trade back a couple spots to get him....
But to your question, if not CB or Edge.... I'd look at either...in no particular order.... TE.....Guard...or Safety.....or maybe in that order... Higs is hurt...we need another TE to go with Allen, and there are a couple I'd draft...but maybe only one of them at 19.....but then I like Ja'Davion Sanders better than Bowers because he's a bigger TE. We need to re-sign Dotson, but if that looks to be too expensive, we could draft another starting guard at 19.... and at safety...I like Fuller, but he's honestly expendable with Laker and Yeast showing promise....and we have Taylor..... We could draft Fuller's replacement at 19 if we don't bring him back.
