There never was a direct quote or source (other than Dashtary) specifically mentioning Kesler. The only indirect quote I can find is from draft weekend: “There was some activity,†MacLellan said. “I think the no-trade clauses have clogged it up a little bit, because not everyone can participate in them. I thought there’d be a little more than there was, actually. “There’s a few things we pursued. They fell through. We didn’t get it done.â€
WaPo.
That may have been stated more of an overall participant in the trade market rather than an involved party so hard to say based on that alone. I could have sworn he was more explicit in referencing their own involvement elsewhere. Of course, it could also have been another player with a NTC so probably grasping but that was the gist of it.
