I doubt "bounce-back season:": the article itself mentions first-season turnarounds haven't happened with Taggart. I am not expecting miracles and a bowl game would be close, considering the gaps in the program and the improvements in PAC rivals.
Fans will have to be patient: we may improve on D (nowhere to go but up) but the offense could be worse because of a lack of tried-and-true WRs and also because opponents know we have no proven second-string QB and hence Justin won't be running much (if he does, he just won't last in the PAC-12; safeties and LBs will decapitate him at some point; he just doesn't have MM's acceleration to get into the smaller DBs hitting zone). That means the zone-read option won't have much mystery and ends or stunting other players can tee off on the RB. 
I'm very much looking forward to seeing Taggart's team/scheme, however, especially how he uses Freeman, Nelson, and some of the new speed guys. The key: new guys need to perform; luck to keep injuries down.
