Bears' Brandon Marshall chasing history

Chicago Bears receiver Brandon Marshall is averaging 7.6 receptions per game this season. So with a slightly better-than-average performance Sunday against the Minnesota Vikings, Marshall could achieve some hefty milestones with plenty of room to spare.

Marshall is nine catches away from hitting 100 for the season, an accomplishment that would place him among the most productive receivers in NFL history. As the chart shows, he would become the fourth player in NFL history to compile four 100-catch seasons in their careers. No one has done it five times, although the New England Patriots' Wes Welker is eight receptions away from doing so this season.

Whenever Marshall gets to 100 catches, he will tie Marty Booker's franchise record for receptions in a season.

We'll figure it all out when the final numbers come in, but I think we can safely project that Marshall is going to finish with the best season for a receiver in Bears history. As we noted Friday, Marshall leads the NFL in parentage of his team's targets (39.2 percent of all throws) as well as the percentage of his team's receptions (41.9) and passing first downs (44.9).

The real question is whether we can quantify it as the most productive year for a Bears player at any position. That will take some apples-to-oranges analysis to compare him to the likes of Sid Luckman, Gale Sayers and Walter Payton.
