Aaaand that's /thread imho.I am confident that if the coaches thought Cross could help the team running the ball differently than how you say they have pigeon holed him, they would.
It comes down to whether or not you think the coaches are doing their job, really. They see this guy every single day, watch all his tape and calculate his successes/failures. Then, they transition what's done in practice to Saturdays. It doesn't matter how hard he works or whether he's the last guy to leave practice or the first - what matters is his ability and how it transitions to Saturdays. It's extremely unwise to do something in practice but then try something completely different in a game. It stands to reason the coaches have evaluated Cross and are using him accordingly.
