4 years peak? That's not a peak, that's a plateau!Very few players maintain their peak consistently for 6 -7 years. That is what you are hoping for if you think we will get 4 years peak Bolton. It is more likely that his peak is past. I posted on this earlier in this thread, only 3 payers older than 26 have wone the AFLCA, the last was Simon Goodwin in 2006. Bolton turns 26 in December. I'm just trying to be realistic.
Given all kinds of things can happen (injuries) that affect performance, what you'd be hoping for, rather, is either 4 years of the kind of consistent quality that would get you top 10 in the Doig, or should their be injuries, then say 2 of the 4 or so years being AA-squad quality or better.
