This is just me being a fanboy. But I'm always ok with the idea of "going with Sproul". This kid is going to be the next Doughty. He was an absolute steal. Size, speed, shot, athleticism, smarts. I legitimately think he'll be a better player than Mantha even, but that's just me.
Anyway, back on topic. Green would help, but I'd definitely not trade too much to get him. AND it would be wise to dump salary where you could to offset the acquisition (Kindl and Andersson).
I think Sproul's going to be good too.
We have some legit D prospects and it's awesome. Which is precicely why, for once, I think they should stay buried in GRs for as long as possible.
