UCF's Josh Robinson made a name for himself by posting the fastest time at the NFL combine. His 4.33 40 time definitely turned heads and pushed him up many draft boards. Teams look for many things when evaluating a prospect, but speed carries more weight than others.
However, there are some concerns regarding Robinson's hip fluidity. Corners who can't make smooth cuts have a hard time sticking with wide receivers.
Wes Bunting of the National Football Post sees Robinson as a good mid-round prospect.
He's fluid, can really run and has the vertical speed to make up for a false step at the college level. He's also a guy who will tackle and isn't afraid to mix it up inside. However, I have a tough time giving any undersized corner a first-round grade who isn't technically sound in his drop and/or isn't real physical off the line.
Robinson isn't a finished product and needs some time to develop. However, his physical abilities will help him gain early playing time. At the very least, he'll see plenty of action on special teams, while his immediate impact on defense might come in a nickelback role.
Depth is very important in the secondary, as an injury can occur at any time. Robinson's early contributions might be limited, but expect to see him earn more playing time as the season progresses.
Robinson will have some learning to do at the pro level, but you can't teach speed. And if he can work on staying with bigger, shiftier receivers, he could develop into a solid contributor for the Vikings.
