I would not like to see Brownlee at SF at all. I love what he provides for the team in terms of doing things that nobody else really does--shot blocks (other than Coker), tip-ins galore/offensive rebounds, and he owns the baseline--which I think will end a game or two before the season is over. He also has good hands for boards and active hands/good length on defense. Him and Mase on the floor together with Hardy could really frustrate opponents and cause a lot of turnovers.
I would like to see him do what he does best and not try to be a SF or outside shooter. He and Evans both try to do too much at times and it really hurts the team.
