Felton could play PG more effectively in LOW dosages, he has been more sucessfull playing SG
He cannot defend PG's because of his big bones and go through the picks
Neither can Pablo or Kidd
Felton's lack of IQ, ability to run a team, and inability to defend PG's will show come play off time, he has been able to keep this down with Pablo starting
Kidd is no longer a PG, NOT a penetration threat, cannot defend most PG's and many SG's, and is not a good PnR PG at his age
Pablo can run the PnR, also a good facilitator, but not much of a penetration threat and moves at 5mph at max speed, and also cannot defend PG's
so no one in a "3 headed" PG trio can actually defend the position and have inabilities to run a team but they make Melo happy and do not steal his highlights
2 of them play SG more effectively than PG
If Pablo can play PG while Felton plays SG efficiently/effectively, I cannot see why Lin could not have played PG, and been much better than what Pablo brings on both ends
