No, I won't assume a terrible campaign is an anomaly for a 29 y/o that's missed 96 games combined in '13 and '14 because of a ACL tear and then went on to produce that abomination in '15. If you have to attach "when motivated" to a player's skill its a problem. He hasn't been that on a consistent basis in years and when all of his biggest stans thought he'd turn up for the postseason, that bytch quit on his team. Hasn't "leads tops the league" whatever the fukk that means in steals since 2011, and his rebounding is insanely overrated. How many times do you watch the man rip uncontested boards from his big men? Do you really think this masks his deficiencies? For the life of me I don't understand why Rondo gets argued over other players because of rebounding totals rather than actual traditional guard skills, like a fukking jumpshot, 1on1 scoring or not bricking free throws like a 7'2 center.
Rondo shot 31% from mid range on wide open attempts this past season. That's 8% below the league average for mid range jumpshots. He shot 39% from the free throw line and even in his best years he's been inexcusably bad from the line. His inability to be a threat from three does impact the game, defenses don't respect him and will happily help off him to double others on the team. He hurts the spacing of any team he plays for and whenever Boogie or Gay try to go 1on1 they'll be hurt by his presence on the floor.
Rondo is a very good passer, but his absurd turnover rate and ineffectiveness on drives (he is NOT the penetrator he once was) dulls his impact as a playmaker. Darren Collison will give you better penetration than him. He does not belong in the same category as a floor general with Chris Paul who turns the ball over at a much less frequent rate while retaining the same innate playmaking ability.
Not sure why you're excluding Collison's recent season, but the biggest difference between him with the Clips in '14 and Kings now is his role, not talent. Collision is one of the best mid range shooters in the league (47% on 179 attempts), gets to and finishes well at the basket and unlike Rondo invites contact where he gets to the line at a good rate (.335 ftr, compared to Rondo's abysmal .133) and actually hits his damn FT's. He was the best spot up shooter on the Kings last season converting 37% of his attempts behind the arc and provides efficient scoring as evidenced by a 57.6 TS% in each of the past two seasons, as compared to Rondo who's been among the most inefficient players in the game for years and is a big liability when he's not controlling the ball which will be a problem playing next to high usage ball dominant players like Rudy Gay and Demarcus Cousins. He's a good defensive player that'll actually commit to giving effort against "trash teams in the regular season" unlike Rondo who's apparently above trying against inferior competition as if that's a real copout. Not even LeBron can get away with that coasting excuse. The Kings will be a better team with Collision on the floor than Rondo because he compliments the team better and he's a flat out better player at this stage of the game. That stance isn't hard to understand if you take off the homer goggles. You aren't in a position here to be insulting other people's knowledge of the game.
