He can if that is his honest opinion and it is based on facts. However, there is a difference between an assertion (claiming something is true) and a fact (something which is indisputable). The most compelling and easily examined facts Jason gives his viewers (whether they were about Layne or Lame) to support of his opinion were;
a) Layne has lifts that are superior to power lifters in a non drug tested federation.
The British Drug Free Power Lifting Association all time records in the 100 kilo / 220 lbs category are 273 k / 600 lbs squat, 215 k / 473 lbs bench and 310 k / 682 lbs deadlift (1). Layne Norton’s best lifts in the 100 lbs / 220 k class are 280 k / 617 lbs squat, 175 k / 386 lbs bench, and a 318 k / 700 lbs deadlift. However, as his best total is 1680 lbs those lifts were not at the same meet (2).
Layne’s squat and deadlift are marginally better than the records of the BDFPA. His bench does not rival the record. At the competition BDFPLA meet on the 6th and 7th April 2013 there were only eight competitors in what would have been Layne’s category (3). It’s only a small federation and not a reasonable depiction of what might be attainable by a natural athlete from a broader selection.
b) Layne carries more muscle than is humanly possible.
The Fat Free Mass Index score for a 195 lbs (2), 5’10” (4) man at 5% body fat is 26.8 (5). Body fat is assumed, it may be higher or lower. The average post steroid era FFMI was 25.4. Arguably training knowledge and practice has improved since then and there is a larger resistance training community. Other contestants in the IFPA and NPA have a similar score to Layne Norton.
It appears that Jason’s purported facts are not indisputable and therefore not facts upon which he could base an opinion honest or not, certainly not in this connection. Layne’s strength is commensurate with the best a relatively small natural power lifting Association has to offer; it does not exceed that. Layne’s fat free mass may be high, but his score is consistent with his fellow competitors and only marginally higher than the average post steroid era bodybuilder. In neither case is Layne’s strength or size appear to beyond the scope of that which might be attainable naturally by a genetically gifted athlete.
