There are 4 offensive tackles that are worthy of pick 19 by most experienced talent evaluators which would fill our biggest position of need. WR would be a luxury pick and not filling any hole. If and only if one these 4 tackles is not present at pick 19 should we consider another position.
I believe we will either have a shot at Zack Martin, and if not Mosely, Shazier, Pryor will probably be there.
I would also be fine with drafting the best guard in the draft in Xavier sua Filo who you can plug right in for the next 10 years.
Using your philosophy we could end up with another porous O-line in 2014 and another 50+ sack season for Ryan Tannehill which he might not survive this time.
