Maybe we have different standards. He's a 6th round pick for a reason. He's 5'11 and weighs just over 200lbs. Some pages have him listed at 6' 215 but I think they're being generous.
Here is part of a critical evaluation of him, please note the first sentence.
"
Evans doesn’t have enough mass to carry appeal as a workhorse. He’s not proficient enough as a receiver to provide immediate passing-down versatility, and he’s not strong enough as a pass protector to give coaches solace in the backfield on third downs. Meanwhile, as a runner — his primary mode — Evans isn’t an elite creator, and he struggles to vary his stride lengths and adapt when faced with early contact.
As exciting as Evans is in space, he is a relatively space-dependent back. Add on an uncertain projection as a receiver and as a pass blocker, and his lack of dimensions is concerning, especially in a modern NFL, where versatility is becoming more and more valuable.
Evans does have the tools to be a multi-phase threat, and in zone-heavy running schemes, where Evans has more space to survey lanes and open up his strides, he could be a truly dangerous rotational component for an offense. The ultimate variable in his progression is whether he can add more versatility to his game. He has starting upside but might ultimately settle as a rotational piece."
I want him to succeed just like I wanted K. Williams to last year. I've consistently wanted a big workhorse RB and Evans isn't that.
