Felton at his best is better than Prig at his best. Pablo takes less chances on offense and therefore has the ability to show flashes of more production in limited minutes BUT this team needs an aggressive PG since that's what benefits Chandler and our shooters. For a strictly half court game, maybe Pablo is your guy but either way he's still not an NBA caliber starter and in my opinion is marginal at best at 35 yrs old.
FYI - Knicks would be a much better team if they were fully healthy and played with more effort consistently. It's that simple.
