Having an older Holt and getting rid of Bruce, the Rams are looking to get younger at WR. Avery, although very raw, has the potential of being the Rams #3 this year. Depending on Bennett, Avery could move up during the year according to early reports.
Being a Holt owner myself, I like getting Avery here and my TS is now full and the extra 2nd round pick would have been traded or cut anyway. So getting the WR I wanted is a nice deal for my roster.
