4th in 1 B&F isn't going to weigh much on the calculations Infamy. I reckon you'd be lucky to get a late 2nd round pick for him.
It's not going to hurt, even the guns of the comp don't always rate highly in their own clubs B&F.
The fact he's still young, an ex #4 pick and has already played over 100 games will mean he won't get a terrible pick as compensation
If it was anything worse than a pick at the start of the 2nd round, I'd rather keep him
