As a long time Bassett fan and follower, I have almost surprised myself here, but I have to lean Forrest. His positional awareness, athleticism and speed remind me of DT, not to mention his spider like lean frame that will only fill in out through time. Despite his thin build, strength is not a problem for him against much stronger builds. I honestly don't know how high his ceiling could be, it seems limitless.
