That would possibly be a good strategy, imo. But we can't "keep" Lock - he's a UFA. We may be able to sign him cheap? But would he fit into the new OC's scheme? Would the new OC want him?Geno just doesn't have it upstairs. Plus, there will be a new offense introduced so Geno's advantage of being here for a long time is over.
Might as well keep lock for 7 million and dump Geno.
