Schmidt was an excellent player in 2014. In 2015, in his 5th year, not so much so as there were more talented players with higher upsides available. Kelly kept playing him because that is what he (and Kelly isn't the only coach that falls in love with certain players) sometimes does. Kelly's penchant for doing this certainly caught up with him in 2016.
While I think Finke is a fine player in his element and was a solid contributor in 2018, there are more talented players with higher upsides that ought to be seeing more time than they are, absent injuries etc. of course. I am not saying that he doesn't make contributions -- he does, although I wouldn't characterize a shield block 40 yards downfield as a "critical" block in the overall play nor one that any number of players would have made. While I know managing playing time is no easy trick with our depth at wr especially when it is likely that Kelly asked Finke to stay and he is a contributor, he just shouldn't be on the first row of the depth chart at wr -- I see him as no more than the 6th guy at wr knowing that there are different roles.
We'll see how playing time is doled out for the rest of the year, particularly after Michigan.
