How about Jeff Allen?
The Kansas City Chiefs guard seemed to be getting the 2014 Donald Stephenson treatment when he wasn't playing for some reason we didn't know. It's ironic then that Stephenson's drop in play in the past few weeks was what led to Allen getting a shot for the Chiefs last week.
He played right tackle last week and played it well. Ben Grubbs was lost to an injury on Sunday and it was Allen who stepped in and played left guard. And he played it well.
The Chiefs need all the good offensive linemen they can get because that has been a cause for concern with this team and Allen has provided a nice in-season bump for the team.
If you had asked me before the season whose contract I would extend - Allen and Stephenson are both in the final year of their deals - I would have said Stephenson. He generally played well when he was in in 2013 and played a more premium position in tackle. But now? It's too early to say definitively the answer is Allen because it's only been two weeks but he has been very valuable to the Chiefs in these past two weeks.
Two positions in two weeks. The Chiefs can use a guy like that.
