To get ready for the NFL Scouting Combine, this week’s mock draft stretches out to three rounds. In projecting 102 picks, some of the strengths of the draft begin to stand out. Everyone is well aware of the quality of the defensive linemen at the top of the draft. But the deeper you go, the tight ends, guards, and cornerback classes show themselves. Going three rounds also means we finally get a pick for the Chicago Bears, who don’t have a selection until No. 87 overall because of the trades that landed them pass rusher Khalil Mack and wide receiver Anthony Miller.
