It’s a good question. Here’s my speculative guess. (Is that redundant?)
Hill and Davis are both backups coming into an offense. As such, they will tend to look hard for a comfort blanket. The 1st WR who gives them some reassuring catches will get a lot of attention.
Right now, that’s Quick. With new QBs, I think it would be a lot to ask to hope for balance between Quick and other receivers.
Having said that, Davis did a great job of finding balance as the game went on. Initially, it was all Quick. But by the end he had completed passes to a wide array of guys. That trend may well continue.
Another point, of course, is that Britt, being more established, is getting more focused coverage. If that is so, it won’t last long.
Quick has suddenly become the real deal. An elite QB would make him an All Pro. Even with modest QBs, he is becoming incredibly productive. Not bad for a guy we all thought was a bust. This brain trust has made a lot of personnel mistakes. Quick is one of their best successes, though it took 2 dead years for him to blossom.
By virtue of the absurd ...
