The thing is with these deals is that it all isn't guaranteed.
DHB most likely isn't going to see all of that money and Jennings is probably going to see more of it....based on achievements.
If the original post is accurate, Heyward-Bey is guaranteed 23.5 million, while Jennings is only guaranteed 15 million in comparison. I agree that this will be addressed in the next CBA, and it's about time.
The only good thing about this signing is that it should help get some of the other 1st rounders inked (and in camp) as well. Seems like there's an awful lot of 1st rounders unsigned for this time of year...
