PTOs I'd like to see.
Austin Watson - punching bag, physical, pker. Would likely be fine with going in and out of the lineup as needed.
Matt Martin - can fight, hits to hurt. Would likely be the same in that he can sit against softer teams.
Both Watson and Martin add toughness and can lessen the fighting load for Xhekaj.
Cal Clutterbuck - really physical, can pk, should still have some skill left to be somewhat useful. Has some fighting prowess there, too.
JVR - one of the best net front presences in the game for a decade, if not longer. Not as good as he was, but could be an option to change things up if the main pp is stagnant.
