They def should release the Spine Bionic Lows, but it's sad that BJ may not get a 3rd sig this coming season. UA should really continue his sig line, along with the other team shoes they're pushing. He committed to the brand early, and though his personal or team stats may not have been fantastic, they should still continue with his line, to show loyalty to a pioneer endorsee.
Was really interested in how UA was going to evolve the Jennings shoeline. He had a lot of momentum going into last season with the "Under the Armour" series and all the streetball tournaments. Also he was the only other player to match KD in sig colorways, IMO. I think UA is thinking they only have like 6 players, and need to maximize brand identity, and it also depends on how BJ plays this year.
Fresh, great points on UA's roster coming into 2013. And you're absolutely right, the Bloodlines' cws were creative, and told stories really well. And Jennings is an enigma, really. The guy can get hot for stretches, but consistency is a huge issue. Well, it could actually be a blessing, if he takes this as a motivation and explodes in 2013 and forces UA into producing another sig for him.
