I actually love this on the new jerseys. Its a more athletic and youthful cut. It's closer to what some college jerseys have been doing:

It's a nice change, imo, that doesn't overstep in deviating from the classic look. It's good to keep things fresh. I'm sure eventually they will return to the classic trim.
Especially since we have this young and athletic team I think it's a welcome addition to ring in a new era. The closeup is not the best part about it. I think the new look translates better when your watching the game on TV or in the stands.
