GM John Elway opened Denver’s draft festivities by landing the offensive tackle he so badly needed (Garett Bolles, No. 20), and he did so without having to trade up. Also on Elway’s checklist headed into the draft: more bulk for the D-line, a big-play option on offense and perhaps a pass-catching tight end. Enter DT/DE DeMarcus Walker (No. 51), electrifying WR Carlos Henderson (No. 82) and TE Jake Butt (No. 145), who is on his way back from a torn ACL. Third-round cornerback Brendan Langley (No. 101) is a high-upside guy, as well, who should benefit immensely from watching the other Denver DBs. Elway also made perhaps the most fascinating Mr. Irrelevant pick ever: QB Chad Kelly. Does he have any chance of sticking on the roster?
