So he should be a great fit for us. Be very different if we switched to a base 2-gap, 3-4 front for example. We will have to see but I assume "Tucker's 4-3 defense" will differ from Lovie's by utilizing more blitzes, fewer straight cover-2 assignments, and have a few hybrid 3-4 looks thrown in there too.
