I think it'd be short sighted to trade him when Hodges, brown, and Humber will all be ufas in a year. Pretty decent chance Lorax gets let go if there's a replacement plan.
It also costs more to cut/trade him than to keep him.
Between the knee, the new defense, and possibly coming to camp out of shape... he's a bundle of red flags and needs a lot of work. Why sell low? Is he going to be a stud? Probably not, but I dont think u make a trade this early. He's basically a struggling rookie.
