I'll give it a shot...
Unless Randy Moss, WRs are a dime a dozen. They're interchangeable. Coaching, scheme and play call are more important than the individual player's ability.
The QB's job is to throw to the open guy whether he's a Ferrari or a Ford F350.
Then there's the diva component which is anathema to the Patriots' philosophy of unselfishness. 1000 paper cuts requires less money and less maintenance.
WR by committee isn't flashy but it works just as effectively for the goal of winning.
Add what you think is needed. I wanted to keep it short and to the point. How did I do?
