Mike Wallace was a different animal altogether. He was the featured receiver, plus he was a free agent. The only thing a team was going to lose was money if they signed him.
Eli and the offense also did great when Cruz put up his monster 2011 numbers so its kind of Chicken or the egg... Cruz's production was what his production was and you cant unlink them.
I dont hear anyone knocking Cruz's numbers down simply for the reason of "its because Eli and the offense were doing great".
It is rather funny how the argument is often "Eli makes his receivers", yet when they suck it's entirely their fault.
