According to Ian Rapoport of the NFL Network, there is interest from the Cleveland Browns to hire Gary Kubiak as their offensive coordinator. The former Houston Texans‘ head coach is currently available and could make sense on a number of level for Mike Pettine and the Browns.
Pettine said in his introductory press conference that he would like to bring in some head coaching experience to his staff. Presumably, he would prefer that experience to be the offensive side of the ball, since he not only has so much expertise on defense but is also bringing in his former assistants to fill many of those jobs. Kubiak not only fits the bill of having experience as a head coach but he has been successful as an offensive coordinator between the Texans and the Denver Broncos.
There is also a mention of the possibility of Ben Tate being a free agent target for the Browns in general, which might only be further intensified if his former head coach comes to Cleveland. Personally, I would rather they use Kubiak to find backs on the cheap in the draft rather than use any sizable amount of money on Tate.
Not only is spending guaranteed money on a running back precarious, but Tate has had problems staying healthy and while he has not missed a ton of games because of it, he is often playing hurt, which could lead to more serious injuries.
