Has Edwards signed with Gibbs? Speculation about #99-Carl Edwards raged through in the NASCAR garage throughout the weekend, with unconfirmed reports that the stock car racing star - now back atop the Sprint Cup standings after Sunday's New Hampshire 301 - could definitely be heading to the Joe Gibbs Toyota operation next season and leaving Jack Roush's Ford operation. No one would say much at all on the record about the Edwards situation. However, it appears something is changing, or has changed. Just what, if anything, isn't clear. And yet still there was little more than more silence Sunday. No one involved was leaping into deny or confirm anything. Part of the speculation involves sponsorship possibilities. Edwards is considered one of the sport's most attractive drivers from a sponsor's viewpoint. And it is believed that part of the driving factor in the Edwards-Gibbs possibility could be Home Depot, the home improvement giant which has 'lost' five straight NASCAR championships to arch-rival Lowe's and #48-Jimmie Johnson.(MikeMulhern.net)(7-18-2011)
