For me, ideally I would like to see Steele, Imanaga, Tallion, Wicks and Hendricks in the rotation. Then spot Assad in when they have a lot of games in a row. This way starters get 5 days rest. Use Brown, Smyly, Wesneski and Keegan in the pen. They can piggyback every so often, too as you suggested. If Hendricks still sucks when he comes back, they may juggle that 4th and 5th spot between Assad, Wicks, Brown and Wesneski so that none of them throw too many innings. And they may use Smyly and Thompson in piggyback roles as well, to limit innings.
