If i was doing a Mariota mock, i'd go for it. Were gonna lose Hakeem Nicks, so i'd go for a weapon to replace him , and i'd grab some lineman to protect him, and a real TE..
1). Marcus Mariota QB Oregon
2). Paul Richardson WR Colorado(perfect fit as Desean Jackson deep threat for Mariota)
3). Hroniss Grasu C Oregon(why not pair Mariota with his stud C?)
4). Deone Bucannon S Washington St
5). Marion Grice RB Arizona St.
6). Larry Webster DE Bloomsburg
7). Denicos Allen OLB Michigan St
If you dig up the dirt in Oakland, you will find Giant bones
