I know you're joking but his contract would be very easy to move if we wanted to.
I don't think we move on from Kmet until we see how Loveland adjusts to the NFL, however.
I could very easily see Kmet on another team next season.
Only kidding in the sense that I know it's a touchy subject. I've posted before that Kmet is a nice trade piece cause his contract, so I agree with your point. Bears can move him... and another team should want a guy of his caliber at the price point.
That said, I'd expect the Bears would do nothing to lose team leadership and talent this year. There's too much on the line and they're probably more likely to keep Kmet and not need him than trade him and risk a gaping hole at TE. If Loveland is a stud by the deadline (or the Bears are a disaster), maybe they'd think about it.
