Pacers don't have salary cap to throw enough salary for Lowry. I believe Lowry's expected contract would fall anywhere between 8-10M/yr, but Pacers is already paying $8M/yr to George Hill. Unless they ship George Hill away, Pacers will be out of competition.
Interesting fact is that most teams already have a solid staring PG or do not have enough salary cap.
Orlando - probably the strongest candidate. Their current starting PG is Jam Nelson, who sucks bad and has Team option for next year. Unless they decide to try Oladipo at Starting PG, they will consider opting out Jam Nelson's team contract and acquire a better PG.
Milwaukee - if they don't consider Brandon Knight as their future PG, then they might be interested.
Sacramento - If Isaiah Thomas does not extend his contract with SAC next year, they might chase for Lowry.
Lakers - If Nash can't recover from injury, they will definitely need a starting PG that will support Kobe. But, if they decide to throw enough money to Lowry, they have less salary caps to fill SF-PF-C positions.
Miami - Chalmers has not extended his contract and Big 3 has player option - where anyone can opt out for a new contract. If any of Big 3 leaves, they might have some cash to throw for Lowry, but not as much as Lowry expects.
All these above teams are "possible" destinations, but I honestly think Raptors
is the ideal fit for Lowry at the moment. Raps have enough salary caps and all other positions are locked in for next year, so the team roaster is in good shape already.
