I'm on board with improving OL/DB/OLB in the first round, but if WR is that you love then why not.
A true bonafide #1 like Hopkins, A brown, julio, megatron, or OBJ can really transform an offense much more than an OG. Everyone keeps saying this team need more playmmakers... I like cohen and howard but there are NO WR's on this team that are play makers. If the bears pick around 8-12 it is likely that guys like chubb, fitzpatrick, barkley and others will be off the board. The bears are more likely to be looking at a top WR or a top OG/OT. If you are looking at top O line you can make very similar comments about being able to find talent in later rounds, just think whitehair.
Also, a lot of people seem to be banking on Pace signing AT LEAST 1 FA WR. I'm hopeful for a big name guy like watkins, allen robinson, or landry... but thinking he will land two is a bit much imo.
