remember old friend, who we are soon to see, ryan gomes as a small forward?
he did a good job, a tweener with way more foot speed than jjj, if ryan is a starter then you have to have 4 really good other starters, he is a very good sub but not a fast enough sf
(side note when he was here I was accused of a man crush on him

so trust me I like his game)
jjj is an offensive pf, he will give big pf troubles because they have to leave the paint to guard him, i love his offensive game and hope the rest comes next year (as a power forward)
as a sf sub with worse speed than gomes he'd be eaten alive, better to go with marquis or sasha, even against a big sf (melo or lebron) jjj is to slow to handle the defensive end
is that enough of a NO ?
