Burtch has a lot of Swift/Peterson in him. Not that blazing athlete that'll make sportscenters top 10, but man, the guy is reliable and plays his role.
And with all of our receivers hype, this is what we have been missing IMO. We need a receiver to be "that guy" who is a sure handed go to guy when we need a pass completed. Blazing speed is great, but I also like the guys who can read the coverage and sit on his route, make the first down catch in traffic and keep the chains moving. I hope he and Westerkamp can fill/excel in this role as well as the two you mentioned above. Throwbacks to guys like Steve Largent or Jay Novacek. Not blazers, but ran great routes with hands like glue.
Great receivers make an average QB look incredible. I hope that the two above as well as KB, Carter and Jamal really step up and improve that aspect (catching) of their game. It would easily make the difference in 1-2 wins next year IMO. And like the fumbles, has shown itself at the worst times.
