I think we need one more offensive threat in the starting lineup. That was probably the idea behind starting Garza but he's better suited going against bench talent rather than starters. As it is, JB and White are overburdened trying to play 2-on-5 against credible defensive teams.
Obviously Tatum would solve the problem, but until/unless we get him back we may need to get creative. I hesitate to jerk Pritchard around too much (especially given how well he's playing right now) but perhaps we could move him back to the starting lineup and give Harper a trial-by-fire off the bench for a few games.
