No. 2: His defensive playmaking, veteran-type of feel as helper
Defensively, Porter has given Cleveland some quality minutes as a point-of-attack option, and with Isaac Okoro out for an extended period because of knee soreness (he's since returned), that helped the Cavaliers for stretches in Porter's minutes. He's not necessarily going to have the versatility of Okoro on-ball on that end, but to a large extent, Porter did a commendable job in that aspect.
Porter's defensive playmaking has been an aspect of his game that has definitely caught Wine and Gold's fans eyes, though, and that's something that has translated from his time at Wichita State.
Porter had remarkable splits in that regard in recent seasons with the Shockers, and so far with the Cavs, he's had 0.6 steals and 0.5 blocks per contest, on robust steal and block rates of 2.0 and 2.5 percent. And extrapolated out on a per-36 minute basis, he's averaged 1.5 steals and 1.1 blocks.
Though he's 6-foot-1, Porter has been a disruptor in passing lanes as a rotator, has shown the ability to come over the top to block shots, even at his size, and his efforts have helped generate transition looks. He can take some fouls at times trying to make plays, but one can appreciate the effort and aggression he's played with on defense.
Porter is again on a two-way deal, and there's a number of others involved, so there's going to be variance in his minutes. However, if he keeps making plays when he's given ample opportunities and helps the Cavs bench, he'd seem to be a realistic candidate to have his two-way eventually converted to a standard deal, especially with the uncertainty in relation to Ricky Rubio.
