4. Dennis Smith Jr.
Sticking with the backup point guard position, Dennis Smith Jr. is certainly one of the more desirable names still available. He served as a jack of all trades for the Brooklyn Nets this past season, adding a good amount of scoring, passing, rebounding and, perhaps the most interesting part, nice perimeter defense for a 6-foot-2 guard. All of that could elevate the Milwaukee Bucks' second unit.
In Milwaukee, he'd slot nicely into the backup point guard opening, giving this team a ball-handler to take the reigns when Lillard catches his breath. Not only would Smith boost the defense, but he'd also be useful in giving this team another athlete, as he can jump out of the gym. The only possible issue is that Smith may be seeking more than a minimum deal, which the Milwaukee Bucks cannot offer.
3. Lonnie Walker IV
Speaking of players who could come in and compete for Milwaukee's starting shooting guard gig, Lonnie Walker IV is still out there. He's proven himself to be a fine role player since coming into the league due to his ability to score, shoot, rebound and play solid defense in spurts. It's a bit surprising that he's still out there for the taking this late in free agency; someone may end up with a steal.
Walker doesn't have the perimeter defensive prowess of someone like Okogie, but he makes up for it with his solid offensive production and electric athleticism. He could give Milwaukee another scoring threat in the second unit, something they've lacked outside of Bobby Portis. It would also help adding an athlete of Walker's caliber to help the transition game. If they can get him cheap, the Bucks should.
