They could certainly move forward without Lee.  I don't really think it's a good idea, but they could.  

 

I really like the PS player Rashad Lawrence (assuming his injury isn't too serious) and Benn is an untapped resource now that he's healthy.

Those guys are solid #3 receivers. Greene could be too. 

 

So - they could actually get by with what they already have on the roster - especially if Greene can get his act together. 

 

i just think Lee's speed is worth keeping around if you can work the number$.
