Seriously, surprised it took this long for someone to say this. Star makes Luke a better player with all the extra attention he draws as it allows Luke to run free. There are lots of pass rushing DT's, especially when we have a few DE's who can slide inside as well, but you don't come across the big space eaters as good as Star will be all to often. If push comes to shove, Star will stay and KK will move on. You also have to remember that Star is a family guy, I'm sure his family is getting settled and might not want to uproot them, so he could take a hometown discount to stick around.
