When we talk about progression - one of the best signs is when your starters become squad players for depth. Lets not throw the baby out with the bath water Fulton is a wonderful professional who always gives 100% and can be a good option when the manager is looking to close a game down (depending on cost).
HOWEVER, having said that, as a coach I look for strong attributes/deficiencies..I am afraid Fulton has some traits that are deal breakers for me in the sort of starting XI we need to build.
1. His grasp of pass and move ends at pass..I would encourage anyone to look at how Allen (best example) is/was always in motion making angles to take the next pass. Fulton makes a pass, and then stands intrigued to see what happens next. It is my belief that any player who is a spectator should pay like the rest of the Jack Army.
2. Jay is totally risk averse, and cannot grasp the equation of risk/reward. If there is a 100% safe pass available (normally sideways/backwards/short) he will take it - often ignoring forward looking options that offer high potential reward. This made him the worst possible partner for Grimes - but makes him useful for closing games down.
3. in the same vane as 1. above, he also stands and watches when he should be tracking runners, and is very slow to sniff out danger. He needs everything in front of him, because runners will get away from him. Add to that (and because he is often late to the party) he has a tendency to lunge into desperate tackles, give free kicks away in dangerous areas and invite cards (Wembley anyone?).
