I'm all for finding that elusive downfield threat/outside receiver. It was just yesterday when Rex Ryan boasted that he felt the NYJ corners matched up extremely well with our outside threats (or lack thereof), which allowed their defense to do the things they wanted to do.
The problem(s) become:
1. Finding that WR in the draft, particularly when you have seen so many fail at the concept of being intelligent/hard working enough to pick up the system
2. The fact that they don't pick high enough
3. The financial compensation that it'd take to bring in a free agent at 10+m dollars per year
4. The hit/miss poor ratio that is often seen, specifically with a harder system--which makes a coach/GM think twice about potentially "wasting" a higher round pick, or taking a gamble at a free agent who has talent
At this point, I think I just want to see 3-4 outside threats brought in, whether that means high picks, middle picks, low picks, highly sought after FAs, UDFAs, or players off the street. They need to keep throwing stuff at the wall to see if anything sticks.
