Wouldn't be surprised if he was in a straight line. Often they are. Kaboul was the fastest in a straight line at Spurs a couple of years ago I believe, beating out Lennon.
I would be very surprised, and I would honestly be shocked if his acceleration and pace was better than Lallana's.
But of course, everyone's gonna disagree on attributes anyway. I'm just still baffled by the 15 they gave Sterling, I don't think that one is even a matter of opinion, it's just wrong.
