We have had posters saying that for years now.
Well, he was on the team for parts of two seasons. And last season the Rams were remarkably short of injuries, and he averaged 3 yards more per punt return. Last season the Rams had an emergency, which is why he was brought back.
This past offseason the Rams made no particular effort to bring in serious competition. I expect real competition for punt returner this year, since Natson just wasn't that good this season, and it has become apparent that the Rams need a punt returner who can actually play another position for roster insurance, not a guy who is not elite as a punt returner, and who is not seriously considered a backup anywhere else. 7.8 yards per return, with more fair catches than returns, is NOT worth a roster spot if they guy doesn't bring anything else to help the team.
Fortunately, now that the Rams have evidence that Natson is not a star punt returner, I have faith that the Rams will bring in real competition this offseason, and likely someone who is not one dimensional.
