The NFL Network’s Mike Lombardi is reporting that there’s talk of quarterback Tavaris Jackson possibly demanding a trade if the Vikings sign veteran free agent Brett Favre. The 26-year-old Jackson would probably be low man on the totem pole if Favre signs, considering the team also traded for Sage Rosenfels earlier this offseason.

Although Jackson is still young and has put up fairly decent numbers thus far in his career, it’s safe to assume that he won’t garner much attention on the trade market. He only has experience in the West Coast offense and he’ll become a free agent at the end of the year, so why would any team give up a draft pick (assuming that that’s what the Vikings would want in return) to acquire him?

It’s only a matter of time before the Vikings sign Favre and while Minnesota might want to try and deal Jackson to get something in return for the former second round pick, there doesn’t appear to be much of a market for him. The Seahawks could be interested because they run the WCO, but all indications are that Matt Hasselbeck’s back is healthy and backup Seneca Wallace already has starting experience in that offense.

Another team that could be interested is St. Louis, who currently employs a walking stick figure at quarterback in Marc Bulger. But considering what they’re paying Bulger these days, the Rams are going to try and get everything they can out of him before finally waiving the white flag on that situation.

The Vikings might inevitably want to hang onto Jackson this season as insurance in case Favre’s arm falls off at some point. I’m sure Brad Childress would sleep a little easier at night knowing he could at least fall back on Jackson and Rosenfels if the Favre experiment backfires.
