It's probably a bit of an overstatement. Ben is no Theo.
That said, Theo, like Ben, got a LOT of criticism when he was here for his free agent signings and trades. His strength at the time, like Ben's, appeared to be the farm system and long term development. But once he got out from under the stranglehold of Lucchino, his talent in player acquisitions became evident.
The team is at the point where the young core is in place. It's at the point where a few key acquisitions could make the team a contender for several years. Ben was not given the chance to see that through.
