Both Mclmore and Olidepo are to small to play the SF position. Best thing for the wizards is pray Otto Porter drops to them, which I think will happen. You have Ariza who's contract ends after this upcoming season and you have the option of bringing back Webster (who they should bring back). Now you keep Otto on the bench for a year groom him and in year you have a nice trio of Beal, Wall and Porter.
Your stuck with Nene for like 4 more years so no point in drafting a big man and Okafor is a really really underrated player. Go with Otto , pray he there at 3 and in a year or two I could see the wizards becoming a nice TEAM like the pacers.
You can build a team through FA, you know. Quite successfully too.
