Would you prefer Rubio to Rondo, given Rondo is likely to come cheaper?
first, rubio plays far better defense now.
second, rubio is less moody and plays hard consistently.
third, rubio is a tiny bit better at 3 pointers over his career (32.2% vs 31.5%) but much better at FT(83.8% vs 60.5%). and as noted above, rubio probably fits better with CBS offense than rondo. but neither is an offensive force.
finally, rubio is 28 years old, rondo is 33 years old.
the big problem with rubio is his paycheck - he made $14.75 million last year. too much for a back up. but if kyrie walks, rubio might be a credible replacement.
