The drafting of Joe McKnight means one thing to me. This is another guy who is shifty, run the ball, and catch, and make people miss. He's not a RB, he's a RB/WR/KR/PR.
The Jets can play a Wildcat package of Brad Smith, Joe Mcknight, and Ladanian Tomlinson. From this package they can:
1. Have Smith Option to Tomlinson, or McKnight.
2. Use a double, or bubble screen to either back.
3. Run draw plays with Brad Smith.
4. Split out Mcknight and/or Tomlinson who would most likely be lined up on LB's if they have only RB's and 2TE's. Defense's would crowd the box with 8 or 9 players, the Jet's play 2 TE's and then split out Mcknight and Tomlinson.
5. Run sweeps, misdirections, and reverses with 2 backs running one way, and the other going the other direction with a wide open field in front of him.
In short, the Jets can now have a package on the field that they can on any play run throw, and option out of. They can keep Brad Smith as the initiator and maximize his skillset, even in a no huddle offense. Shift the players at the line according to the defense and never miss a beat. It's just another wrinkle to the offense that I can absolutely see coming.
