I am not a huge fan of the slow mesh, but I guess imitation is a flattery. The slow mesh does put pressure in the LB's and safeties, but it basically turns every running play into a draw play. The OLine has to hold blocks longer, (and they are really pass blocking instead of run blocking), and the RB is not getting a running start at the LOS. I think a mixture of slow mesh and regular hand-offs would be the most effective as the LB's and safeties would always be on their heels reading the play and slow to respond to a quick hitting regular hand-off.
