Jalen is also in the prime of his career and his accomplishments are far from over. Way too early to judge where he stands in comparison with Knicks all time greats imho, but he will definitely be way up there when he is done.
As Paultz points out, Clyde was clearly surrounded by far more talent than Jalen has to work with. For better or worse, the greats are often judged by how successful their teams were. If Jalen ever won a championship with this Knick team, he would be up there at the very top.
