I was quite interested regarding Jones as PAK coach about a decade back (precisely after Lawson was sacked and then again before Whatmore was appointed), but since then guy hasn't added much in his resume. He was one of the best ever ODI batsmen and a top class Test batsmen as well, with experience of over two decades in Counties & Shields, which is enough experience for such high profile jobs, but guy is now 58, with very little serious coaching experience - something will hunt him every moment in PAK cricket media circle, if eventually appointed. Surely, PAK is going to lose some games whoever is Coach/Captain and Jones with his experience (lack of it) as Coach, will always be on firing line; PCB as well for appointing him.
I read, he completed his Level 3 (or 4) Badge from Queensland Academy, which probably is the highest level coaching badge along with MCC Level 4, therefore technical qualification isn't any issue. He was a brilliant thinker of the game, once appointed Australian VCaptain (would have been Captain as well, but for the suspicion of dodgy acts), and a great analyst, but his coaching career based on PSL (read T20) credits ZERO Value to me. On potential, I don't mind him, but 58 is the age when International coaches plan to retire, not start career.
Personally, I think it's too late now - PCB should either appoint a former great (Misbah looks to be front runner) which will be easier to justify regardless of team's performance; or go for a reputed known face, with distinguished playing career; like Andy, Lehman, Moody or Mahela to keep PAK cricket media sane.
