When you have a WR that can create separation, and run good routes(something none of the rams WR can do ) then that makes life easier on the QB and allows you to break the defense down especially when everyone will be stacking the box against Gurley.
Yes. It does make life easier for a QB. Yes, it can help Gurley. But there's a problem you're overlooking. If defenses don't respect your passing game, it's not going to make life easier for Gurley. And the WR's ability to create separation is severely negated by a bad QB that is inaccurate, slow with his reads, or late on his throws.
You want to help Gurley out? You want to bolster the passing game? You bring in a franchise QB. You don't draft a WR to try and make your backup caliber QBs work. Because that doesn't work. You can bring in an elite WR and he'll still make very little difference if your QB sucks. However, if you bring in an elite QB, he can still make a MASSIVE difference even if your WRs suck.
Even if we bring in a QB he will have no one to throw to and he will look like our QB's did this past season.
No, he won't because our QBs in 2015 were terrible. If this team actually brings in a good, talented QB, he'll be far better than what we saw in 2015 and we'll see a major boost to our W-L record. Something a WR won't provide.
Drafting a QB and inserting him into this offense is just asking for him to fail.
No, it's not. He'll be walking into a situation with a talented defense and running game. Isn't that exactly the situation Russell Wilson walked into in Seattle?
Hell, you might find when we bring in a legitimate QB that Tavon Austin and Kenny Britt were actually better WRs than we knew them to be.
