As an All-Pro punt returner, Olszewski is already a roster lock. But the more you can do, the more valuable you are to Bill Belichick. I’m reluctant to say that Olszewski is on the Troy Brown, Wes Welker, Julian Edelman trajectory where he’s going to develop into a great slot receiver and returner. But Gunner keeps making plays in live team drills. On Tuesday, Olszewski dusted cornerback D’Angelo Ross on a crossing route where an explosive route break caused Ross to fall to the turf. If the parallels between Olszewski’s career and Edelman’s continue, then this would be the year where he starts to make an impact as a receiver.
