this does sound like a real scenario. If it was accompanied by a trade down to picks 30 to 32, and take Mond with the 5 year option, while picking up an extra pick(s) it would seem like a good move.
Then again, if he could get an OT at #20 and still get Mond, that would be better, even if it means no 5th year option - and from the "win now to save your job" point of view, that 5th year is probably worth less to Pace and Nagy than an OT - or SHOULD be. I lost an infamous bet last year betting that Pace and Nagy would understnad they have OT needs, and apparently they didnt see it, and it cost us last year.
