My advice to all of those professional and fan forecasters of the 2018 NFL draft in the hours leading up to the first round on Thursday: Be careful with the absolute statements. Three of the first four picks are controlled by two men (Cleveland GM John Dorsey at one and four, GM Dave Gettleman of the Giants at two) who could work for the CIA. There’s an inordinate number of teams very high that I believe will want to trade down, and perhaps for only moderate value because of the strength of the second and third rounds and the thinness of the first round. “This year it seems like there’s no normal,” San Francisco GM John Lynch said on Saturday. The Niners pick ninth in the first round. “I’m having our analytics guys go over every scenario we could face at nine, and there could be 50 of ’em.” And so this year’s mock first round is a dart-throw if there ever was one. Wish me luck. Trades (and wild guesses) included.
