For now Arrow might seem surplus. But the majority of our starting pack is ageing, we can't just expect to be able to replace them with rookies. Most of our young guys seem to be built for impact, Arrow looks to be the only genuine workhorse, so even if he doesn't get a starting spot he needs to gain experience on the bench. By the time the next position opens up it'll be one of the guys who's been biding their time on the bench, likely for 2-3 years, and at this point we have no idea who's going to cut the mustard.
