Start Masterson over Deablo?

This was interesting. Looking at PFF scores, they have Divine Deablo rated at 58th out of 81 linebackers (61.6). This makes him below average. He has done a decent job but I think he's been better because of Robert Spillane being there with him. Luke Masterson, on the other hand, has a score is 85.4. He currently doesn't have enough reps to give him a ranking but this would put him in the top 10 for linebackers. I don't think he maintains if he were to start but would he better than Deablo? When I've seen him play, he's looked good. Is it worth possibly giving him more reps?
