Ok....first off...
Tomlinson isn't even an option...he's not a FA after this year like someone said earlier....he has another year on his contract after this upcoming season, and the rumor that he wants to play for the Cowboys is bunk as well, although he did grow up in Texas...he just got a lightning bolt tattooed on his calf this past off-season. That's how dedicated he is to San Diego, the San Diego owner isn't selling the team, and they're in negotiations with the city on a brand new stadium...the GM for that team already stated that LT will be the highest paid RB in the league when his contract runs up....
To get him it'd take more than Sam, Wally and a 1st...try something similiar to what the Bucs gave up to get Gruden...mulitiple 1st rounders and 2nd rounders. That team isn't gonna give up Tomlinson(the best offensive player in the league) for Sam and a 1st....
I think Anthony Thomas is a possibility....maybe Onterrio Smith...guys like Tomlinson are untouchable....
