It's a natural question: Could the San Francisco 49ers show interest in Cleveland receiver Josh Gordon?Gordon is a talented receiver who is reportedly on the trading block. The 49ers have a big hole at the position and a surplus of draft picks. So, is a deal possible?Well, yes, anything in the NFL is possible. But I would say it isn't likely.Gordon has had some off-field issues and with the 49ers knee-deep in the Aldon Smith saga, it might be very difficult for the team, both internally and in the community, to take on another potential problem player.
