I would look to keep Ingram, Ward, Pringle, D Williams, Long, Burton, Nnadi, Gore, Watts. Don't want to give a big contract to them but I'm not sure if any of them would ask for it. Don't care about guys like Henne, Blythe, McKinnon, Bell, Reed, etc.
HB and Brown are all about economics. I wouldn't pay top money to either so they should only stay for the right amount IMO. That's a bit tricky as HB will be 30 this year so will look for as much money as he can and Brown simply left Baltimore to maximize his market value.
We should be staying away from Niemann, Dirty Dan, Robinson, Okafor, Hughes, but I suspect Robinson will somehow be back again.
