Spargo is a smart kick and reliable decision maker when he can find space but ultimately, is slow, undersized and regularly seems to lose one on one contests quite convincingly.
Pickett and Chandler are ahead of him at this stage and Henderson is giving it a really good shake and deserves to continue the momentum he's built in the last few weeks.
Spargo back to Casey, he should have been given several weeks to build some fitness and form before being considered for selection. He was brought in underdone last year and all it did was aggravate his injury. I personally believe that at worst, he is a solid depth player and at best, should remain in the fringes of the best 22 unless he can add another trick to his bag.
