Which is good enough to be 4-0 on the back of an excellent defense but still pretty mediocre (much like Retzlaff). Obviously Wilson has more upside, but it's far from guaranteed he improves enough to be a quality starter at this level. He honestly reminds me of Jake Heaps first season, but without some of the physical upside Heaps had.
Not saying I wouldn't take him on this team, but I don't see why so many CBers seem to salivate over Isaac other than his association with his brother. Kid looks fine, maybe he keeps getting better. But at this point, good chance he wouldn't even be starting for us, and that's a low bar as it is.
