"are you worried," also no. I'm not necessarily confident that tanner will have a ridiculously good year. Complex offense plus his lack of experience as the starter in said offense, as well as the cumulative uncertainty of his supporting position groups on offense, and can't use the word "confident" about a productive offense being a sure thing.
But I'm not worried. Tanner has been good enough before to get the job done, and with this being the second year of the system on offense, I can use the word confident when it comes to whether I think the offense will be better.
