Adam Copeland is joined by KNBR 49ers Pre & Postgame Show Radio Host John Lund to talk about how the 49ers look heading into their 1st preseason game. John talks about how Trey Lance has looked so far in camp and if there is any concern with the "numbers" he has put up. They break down the 49ers backfield and how they are very different then last season. John talks about how it looks like Brandon Aiyuk is ready to take the next step. And how the o-line is very inexperienced and has a few question marks.

-You can hear John on KNBR 680/104.5 with Greg Papa 10a-2p Monday-Friday & you can hear him on pre/postgame of 49ers games.
