I think Thornhill is definitely the best pick by the Chiefs this year. Instant starter with solid performance for a rookie. Looks to have good upside as well. Fenton had some good plays but not a consistent starter yet, however he has been a nice surprise considering the late pick.
The rest are all question marks that we have to wait and see. Overall I think we get a D in terms of the drafted players but that has been the story for this regime ever since day one. Besides Hunt & Hill starting from day one we never had multiple rookies contributing at a solid level, they seem to focus on future potential rather than short term talent, but we don't seem to be as good in long term evaluation of talent for later picks.
