Unless the C's develop or trade for a starting, offensively competent, PG, bringing IT back off the bench doesn't solve anything--it just makes the C's starting O incompetent again.
Also, no matter what, the C's only have five competent shooters from the 3. Probably best to maximize them by having IT, AB, Crowder, and KO starting and playing 30+ minutes and Jerebko off the bench for 15 or so. But that means they can't afford any hockey substitution patterns, because their bench is offensively challenged without help in spacing. (E.g, albeit inefficiently, Sully can pour in the points off the bench if he's got a couple of spacing starters still in there with him.)
