You need WRs. We had a great group of WRs in 2017. It has gone down hill since then.
The fact that Coach P couldn't get WRs (left a joke behind), GRob lucked into one good WR, Marrone struggled to get quality WRs, Shafer was so so, and Babers cannot get anybody should tell you all you need to know.
We should probably go the running QB and ground based O route. Which happens to also be easier to block for. It doesn't have to be boring running, look at what Rich Rod was able to do. Or Malzahn's O. I don't think these guys are fits here but we can look for the next one of Chadwell, Leipold, Klieman, J. Smith, Satterfield.
