At lb where he apparently plays best we already have 4 players competing for one spot. And at lm we have one, and another who is capable available for one spot
Not really 4, if we're considering Harding as possible starter then we might as well count the season over now. That'd be like saying we're considering Barnard for a starting spot up front - we're not. And not Shaw, really, he'll play here and there but he isn't in contention to start. Buttner would be competing with Fox for the starting job.
