Sh*t the bed on undrafted FAs

I feel like with the amount of talent that slipped through the cracks post draft we could gotten atleast one player who everyone was raving about in the later rounds.  Guys I saw at a glance who didnt get drafted were:Victor Ochi DLKeyarris Garrett WRJonathan Jones CBJack Allen CDenver Kirkland OLOni Omoile OLAziz Shittu DESteve Longa LBTyvis Powell SI haven't heard of any of the guys we picked up.  I know the point is to find those small school gems here but some of these guys above were studs at bigger competition.  http://www.nfl.com/news/story/0ap3000000658827/article/2016-undrafted-freeagent-deals-for-all-32-nfl-teams
