He likely isn't mobile enough to play the 90 minutes, but as a last 15-20 minutes when we face a backs-to-the-wall low block - like Newcastle and Forest - he doesn't need to be. His sheer size plumbering around a crowded last third/18 yard box would cause problems.
With 5 subs available, it seems crazy to discount him as an option. Could be the source of a few points to keep us up.
