Hayward without a doubt for me. He is a clear upgrade over Crowder, just a brief look at the stats shows he's much better at getting to the line and seems to be performing very well defensively and on the boards. More importantly he's also quite proven as a closer and that's what we are looking for.
Yes it would mean that one of our guards or wings is likely to be moved but I think that is ok. We aren't picking up our next great big man in free agency, in the short term it will be through trade and if not it will be long term through the draft. A package based on one of our guards should be able to get us that big man, Hayward makes that possible
