New sod eight weeks ago developing light green patches and strange looking grass blades. What's wrong here?

A Professor of Agriculture/Grasses/Weeds said the new sod must be removed immediately and new sod laid. I will not need to pay anything. He also said RoundUp not needed since spores have not yet formed, Wonder how the sod company will make certain this will not happen again.

It looks like nut grass and common Bermuda.

Final determination =. Annual Bluegrass growing in bluegrass- rye sod.

New blue-rye sod was installed yesterday, OMG-- it has many clumps as in the photo. Anyone know what it is? Blades go in all directions. Will it overtake the lawn?
