Yes any pick is better than nothing, and what he has done for the team I like the most I'd like to think they would respect his wishes. Of course they didn't with Barry Sanders but that was different.
I'd seriously be pissed as a Lions fan if they didnt respect him and offer a fair trade to teams he wants to play for. I'd hope for a 3/4 round pick or hell even a player honestly! The pats have several young underperforming WRs I'd take in a swap for a possibility of success.
I wish he liked a team that we could offer him and our #1 to move up in the first but that's not likely at all.
