From Pro Football Weekly:
Word is the most impressive Niners rookie so far this offseason has been fourth-round pick Michael Robinson, who’s being thought of initially as a third-down back but could end up filling a number of roles. Robinson’s running style reminds longtime Niners watchers of a much bigger Charlie Garner in that he always seems to move forward when carrying the ball. In addition, the former Penn State quarterback appears to be a very natural, fluid receiver.
Way to go, M-Rob!
